Participants

Reaction Steps

5.7 g of 4-(trifluoromethyl)benzoic acid and 4.0 g of 2-methoxybenzylamide were dissolved in 100 ml N,N-dimethylformamide, and 4.8 ml diethyl cyanophosphonate and 4.2 ml triethylamine were added under ice-cooling. The reaction mixture was stirred at room temperature for 16 hours, then poured into ice-water and extracted with ethyl acetate. The organic layer was successively washed with 1N hydrochloric acid and brine, dried over anhydrous magnesium sulfate and the solvent was evapoarated. The residue was subjected to silica gel column chromatography, and from fractions eluted with hexane-ethyl acetate (2:1), 8.7 g of N1-(2-methoxybenzyl)-4-(trifluoromethyl)benzamide was obtained.
