Reaction Steps

18.6 g 3-(4-Trifluoromethyl-phenyl)-propionamide and 42.8 ml ethyl 2-chloroacetoacetate were mixed and stirred at 150° C. for eight hours. Excess ethyl 2-chloroacetoacetate was removed in vacuo (oil pump) and the residue purified by chromatography on silica gel with the eluent petroleum benzene:ethyl acetate=3:1 to obtain 13.75 g 4-methyl-2-[2-(4-trifluoromethyl-phenyl)-ethyl]-oxazole-5-carboxylic acid ethyl ester as an oil.
