Reaction Conditions

Reaction Steps

A mixture of methyl 2-chloro-4-(4-chlorophenyl)-5-oxazolepropionate (2.00 g), 2-mercaptopyrimidine (819 mg), anhydrous potassium carbonate (1.10 g) and N,N-dimethylformamide (10 ml) was heated to 100-110° C. and stirred for 4 hours. The reaction mixture was poured into water (100 ml) and extracted with ethyl acetate (100 ml×2). The organic layer was dried over anhydrous magnesium sulfate and then concentrated, the residue was subjected to silica gel column chromatography, and methyl 4-(4-chlorophenyl)-2-(2-pyrimidinylsulfanyl)-5-oxazolepropionate was obtained as a yellow oil (1.42 g, 57%) from an ethyl acetate-hexane (1:4, v/v)-eluted fraction.
