Versuchsvorschrift

As described in Example 37, ethyl 2-(4-chloro-3-nitrophenyl)-4-methyl-5-thiazolecarboxylate was reacted in 1-methylpiperazine, and the resulting ethyl 4-methyl-2-(4-(4-methylpiperazinyl)-3-nitrophenyl)-5-thiazolecarboxylate was hydrolyzed by a conventional process to give 4-methyl-2-(4-(4-methylpiperazinyl)-3-nitrophenyl)-5-thiazolecarboxylic acid (yield: 58%).
