Procedure
In the same manner as in Example 28, methyl 3-thiocarbamoylbenzoate was reacted with 3-trifluoromethoxyphenacyl bromide to obtain methyl 3-[4-(3-trifluoromethoxyphenyl)-2-thiazolyl]benzoate. The product was recrystallized from ethanol. Yield: 34%. Colorless prisms. Melting point: 84 to 85° C.
