The name of this compound is complicated, and it is disassembled according to the naming rules of organic chemistry. "methyl" is a methyl group, indicating the existence of a methyl group connected to the main body; "4-methyl" means that there is a methyl substitution at position 4 of the thiophene ring; "3 - [ (N - propylalanyl) amino]" means that position 3 is connected with an amino structure modified by N-propylalanyl, in which the alanyl group is the acyl group formed by the alanine residue, and N-propyl means that the propyl group is connected to the amino nitrogen atom; "thiophene-2-carboxylate" indicates that the main body is a thiophene-2-carboxylate structure; "hydrochloride (1:1) " indicates that the The compound is hydrochloric acid, and the hydrochloric acid is bound to the main body in a ratio of 1:1. In summary, its chemical structure is based on the thiophene ring as the core, with methyl, nitrogen-containing modifying group and ester group substituted at specific positions, and forms a salt structure with hydrochloric acid.

The physical properties of methyl 4-methyl-3- [ (N-propylalanyl) amino] thiophene-2-carboxylic acid hydrochloride (1:1) Although this substance is not contained in the ancient book Tiangong Kaiwu, it can be deduced according to common sense and the properties of similar compounds.
The appearance of this compound may be crystalline, because it is an organic salt, many organic salts are crystalline. From a structural point of view, it contains thiophene ring, ester group, amino group and hydrochloride part. The thiophene ring has a certain stability and conjugate structure, or makes this substance have a certain melting point range.
Ester-COOCH-fraction, because it contains carbonyl and methoxy groups, or affects the solubility of this substance, it may have a certain solubility in organic solvents such as ethanol and acetone, but its solubility in water may be limited, because the ester group itself is not hydrophilic.
Amino-NH-fraction, because it has a lone pair of electrons, can bind with protons, showing a certain alkalinity. The hydrochloride fraction can increase the solubility of this substance in water, because it interacts with water molecules after ionization. Therefore, overall, this substance is more soluble in water or better than no hydrochloride.
And because it contains a variety of functional groups, the intermolecular forces are complex, or it has a certain hygroscopicity. In terms of melting point, or due to the interaction of various groups in the structure, the regularity of molecular arrangement is affected, and the melting point may be in a certain range.

Its density may be in the range of common organic compounds. Due to the presence of sulfur atoms and propyl groups, the relative molecular weight increases, and the density may be slightly larger than that of ordinary hydrocarbons. However, in order to know the exact physical properties, it is necessary to test in detail experimentally, which is only speculated from the structure and analogs.

To prepare methyl 4-methyl-3- [ (N-propylalanyl) amino] thiophene-2-carboxylic acid hydrochloride (1:1), the following ancient method can be used.
First take appropriate starting materials, such as compounds containing thiophene structure, which should have a group that can be modified into a carboxyl group at the 2nd position of the thiophene ring and a methyl group at the 4th position. And reagents containing amino and propyl alanyl structures are required.
In the reaction system, with suitable organic solvents, such as dichloromethane, N, N-dimethylformamide, etc., to create a reaction environment. Add a condensing agent such as dicyclohexyl carbodiimide (DCC) or 1 - (3 - dimethylaminopropyl) - 3 - ethyl carbodiimide hydrochloride (EDC · HCl), and add a catalyst such as 4 - dimethylaminopyridine (DMAP). The raw material containing the thiophene structure is condensed with N-propylalanyl reagent to form an intermediate of 3 - [ (N - propylalanyl) amino] thiophene-2 - carboxylic acid.
Subsequently, the carboxyl group of the intermediate is esterified. Take an appropriate amount of methanol, add concentrated sulfuric acid or p-toluenesulfonic acid and other catalysts, heat reflux, and convert the carboxyl group into a methyl ester group to obtain methyl 4-methyl-3- [ (N-propylalanyl) amino] thiophene-2-carboxylic acid ester.
Finally, dissolve the esteride in an organic solvent, pass into dry hydrogen chloride gas, or add an appropriate amount of ethyl ether hydrochloride solution to form a salt of the amino group, resulting in methyl 4-methyl-3- [ (N-propylalanyl) amino] thiophene-2-carboxylic acid hydrochloride (1:1). During the reaction process, thin-layer chromatography (TLC) or high-performance liquid chromatography (HPLC) is required to monitor the reaction progress to ensure that each step is complete, and the product is purified by column chromatography or recrystallization to obtain a high-purity target product.
