Reaction Steps

To a solution of 226 mg (1 mmol) N-methyl-3-o-tolyl-isonicotinamide in 10 ml tetrahydrofuran were added dropwise 1.3 ml (1.3 mmol) 1M potassium hexamethyldisilazide solution in tetrahydrofuran at room temperature. The white suspension was stirred for 30 min at room temperature and 0.18 ml (1 mmol) 3,5-bis(trifluoromethyl)benzyl bromide were added at the same temperature. The light brown suspension was stirred for 1 h and water was added. The aqueous layer was separated and washed with ethyl acetate. The combined organic layers were washed twice with brine, dried (magnesium sulfate) and evaporated. Chromatography of the residue afforded 440 mg (97%) of the title compound as a light brown oil.
