Reaction Conditions

Reaction Steps

A mixture of methyl 4-thiocarbamoylbenzoate (1.00 g), 2-trifluoromethyphenacyl bromide (1.50 g) and N,N-dimethylformamide (3 ml) was stirred at 120 to 130° C. for 3 hours. The reaction mixture was poured into water, and precipitated crystals were collected by filtration and then subjected to a silica gel column chromatography. From a fraction eluted with ethyl acetate-hexane (1:4, v/v), methyl 4-[4-(2-trifluoromethylphenyl)-2-thiazolyl]benzoate (1.01 g, yield: 54%) was obtained. The product was recrystallized from hexane-toluene to obtain colorless prisms. Melting point: 122 to 123° C.
