The method of preparing ethyl 2- [[ (2E) -3- (furan-2-yl) prop-2-enoyl] amino] -4, 5-dimethylthiophene-3-carboxylate, can be done according to the following steps.
First, start with 4,5-dimethyl-3-thiophenecarboxylic acid. React it with a suitable reagent to convert the carboxyl group to a more active form, such as acid chloride. This step can be done by adding a chlorination reagent, such as thionyl chloride (SOCl -2), to 4,5-dimethyl-3-thiophenecarboxylic acid and stirring the reaction at a suitable temperature. Sulfuryl chloride reacts with a carboxyl group to form 4,5-dimethyl-3-thiophenoformyl chloride, while sulfur dioxide and hydrogen chloride gas escape.
Times, prepare (2E) -3- (furan-2-yl) prop-2-enoyl moiety. This structure can be constructed by condensation reaction with suitable reagents starting from furfural. For example, furfural reacts with malonic acid at an appropriate temperature in the presence of a basic catalyst such as pyridine to produce (2E) -3- (furan-2-yl) acrylic acid. Subsequently, this acid is converted to its corresponding form of acid chloride, which can also be treated with thionyl chloride to give (2E) -3- (furan-2-yl) prop-2-enoyl chloride.
After that, 4,5-dimethyl-3-thiophenoyl chloride reacts with (2E) -3- (furan-2-yl) prop-2-enoyl chloride. In an alkaline environment, such as triethylamine, the two carry out a condensation reaction to produce ethyl 2- [[ (2E) -3- (furan-2-yl) prop-2-enoyl] amino] -4, 5-dimethylthiophene-3-carboxylate. During the reaction, triethylamine can neutralize the generated hydrogen chloride and promote the forward reaction.
After the reaction is completed, the product needs to be isolated and purified. The product can be separated from the reaction mixture by column chromatography with suitable stationary and mobile phases to obtain high purity ethyl 2- [[ (2E) -3- (furan - 2 - yl) prop - 2 - enoyl] amino] -4, 5-dimethylthiophene-3-carboxylate.
