5-[(1R)-1-(2,3-dimethylphenyl)ethyl]-1H-imidazole hydrochloride (1:1)

This is a problem related to the naming of organic compounds, and it is necessary to analyze complex naming and give chemical structures. However, due to the non-standard and difficult-to-clarify parts of the naming expressions given, it is difficult to accurately determine the structure. The following is a derivation based on understanding:
1. ** Analysis of key groups **:
- " (1R) -1 - (2,3 - dimethylbenzyl) ethyl" indicates the presence of a chiral center (1R), and there is an ethyl group attached to the benzyl group containing 2,3 - dimethyl. The chiral carbon-linked ethyl group has a specific configuration, and the benzyl phenyl ring has a methyl group at the 2nd and 3rd positions. < Br > - "5 - [ ] - 1 H-imidazole-4-carboxylic acid" shows that the main body is an imidazole ring, the 1-position hydrogen is not substituted, the 4-position carboxylic acid group, and the 5-position is connected to the above " (1R) -1- (2,3-dimethylbenzyl) ethyl" group.
2. ** Structure Description **:
- With an imidazole ring as the core, it is a five-membered heterocyclic ring containing two nitrogen atoms. The 4-position carboxylic acid group (-COOH) appears as a carboxyl group connected to the ring. < Br > - The 5-position is connected to " (1R) -1- (2,3-dimethylbenzyl) ethyl", that is, the ethyl is first connected, the specific chiral carbon of ethyl is then connected to benzyl, and the benzyl phenyl ring has methyl groups at the 2 and 3 positions. The chemical structure of
is based on an imidazole ring and a specific substituent. Although the naming is not standardized or deviated, it has been reduced as much as possible according to a reasonable understanding.

To prepare 5- [ (1R) -1- (2,3-dimethylbenzyl) ethyl] -1H-indole-2-carboxylic anhydride (1:1), the following ancient method can be used.
Starting with (1R) -1- (2,3-dimethylbenzyl) ethylamine, with a suitable halogenated indole-2-carboxylic acid ester under the catalysis of a base, react in an organic solvent. For bases, such as potassium carbonate, sodium carbonate, etc., acetonitrile, N, N-dimethylformamide are preferred for organic solvents. The purpose of this step is to replace the amino group of (1R) -1- (2,3-dimethylbenzyl) ethylamine with the halogen atom of halogenated indole-2-carboxylic acid ester by the method of nucleophilic substitution to generate the corresponding amide intermediate. During the reaction, the temperature is controlled in an appropriate range, usually between room temperature and 50 degrees Celsius, sometimes or even tens of hours, and the process is monitored by thin layer chromatography.
Wait for the amide intermediate to be obtained, followed by the method of hydrolysis. Add a suitable base to the water, such as sodium hydroxide, potassium hydroxide solution, and co-heat with the amide intermediate. After hydrolysis, adjust the pH of the system to acidity with acid to make the carboxylic acid precipitate. The product was separated, washed and dried to obtain 5- [ (1R) -1- (2,3-dimethylbenzyl) ethyl] -1H-indole-2-carboxylic acid.
Finally, the carboxylic acid is heated with an appropriate amount of dehydrating agent to prepare 5- [ (1R) -1- (2,3-dimethylbenzyl) ethyl] -1H-indole-2-carboxylic anhydride (1:1).

Temperature control varies depending on the dehydrating agent, acetic anhydride, about 60-80 degrees Celsius; phosphorus oxychloride, room temperature or slightly higher. After the reaction, the product is purified by distillation, column chromatography, etc., to obtain a high-purity target.
