Reaction Steps
A mixture of 1.5 g of 3-chloro-2-(4-cyano-3-hydroxyphenyl)-5-trifluoromethylpyridine, 1.2 g of bromomethyl cyclopropyl ketone, 1.5 g of potassium carbonate and 50 ml of anhydrous dimethylformamide was stirred for 40 hours at 23° C. After addition of 200 ml of water, the mixture was extracted three times with 50 ml of methyl tert-butyl ether each time. The combined organic phases were washed with 50 ml of water, then dried over sodium sulfate and concentrated. The residue which remained was crystallized by triturating with n-hexane. Yield: 1.6 g of white crystals having a melting point of 115°-116° C.
