Reaction Conditions

Reaction Steps

A mixture of 4-chloro-3-methoxy-2-methylpyridine (7.8 g), 2,2,2-trifluoroethanol (24.7 g) and potassium t-butoxide (27.76 g) was heated at 110° C. for 18 hours, then concentrated, diluted with water, and extracted twice with chloroform. The extract was dried, from which chloroform was evaporated, and the residue was purified by column chromatography on silica gel (chloroform-methanol (400:9)), to give 3-methoxy-2-methyl-4-(2,2,2-trifluoroethoxy)pyridine (5.12 g) as a white or pale yellow solid.
