Reaction Steps
340 mg of 3-chlorothiobenzamide was dissolved in 10 ml of ethanol, 570 mg of diethyl bromomalonate was added to the solution, and the mixture was heated at 60° C. for 2 hours. After the reaction mixture was cooled, and the resulting crystal was collected by filtration and recrystallized from ethanol to give 408 mg of ethyl 2-(3-chlorophenyl)-4-hydroxy-5-thiazolecarboxylate. This product was hydrolyzed by a conventional process to give 306 mg of 2-(3-chlorophenyl)-4-hydroxy-5-thiazolecarboxylic acid (yield: 60%).
