Procedure

As described in Example 37, ethyl 2-(4-chloro-3-nitrophenyl)-4-methyl-5-thiazolecarboxylate was reacted in morpholine, and the resulting ethyl 4-methyl-2-(4-morpholino-3-nitrophenyl)-5-thiazolecarboxylate was hydrolyzed by a conventional process to give 4-methyl-2(4-morpholino-3-nitrophenyl)-5-thiazolecarboxylic acid (yield: 71%).
