Procedure

In 10 ml of pyridine was dissolved 1 g of 2-(3,4-dimethoxyphenyl)-4-(1,2,3,4-tetrahydroquinolin-6-yl)thiazole. Thereto was added 0.44 g of benzoyl chloride at 0° C., and the mixture was stirred for 5 hours. The solution was concentrated and mixed with ethanol and water in this order. The resulting crystals were collected by filtration and recrystallized from ethanol to obtain 0.7 g of 2-(3,4-dimethoxyphenyl)-4-(1-benzoyl-1,2,3,4-tetrahydroquinolin-6-yl)thiazole as a light yellow powder.
