Participants

Reaction Steps

The same operation as in Example (91c) was performed using 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid (50 mg, 0.29 mmol), thionyl chloride (3 mL), pyridine (5 mL) and ethyl 2-(4-aminophenyl)-4-methyl-1,3-thiazole-5-carboxylate obtained in Example (94b) (113 mg, 0.43 mmol), to obtain 96 mg of the title compound as a pale yellow solid (80%).
