A mixture of 0.40 g of 2-amino-4-(trifluoromethyl)phenol, 0.38 g of 3-methoxymethyl isonicotinic acid, 1.30 g of BOP reagent, 0.30 g of triethylamine, and 20 ml of DMF was stirred at room temperature for four hours. Water was added to the reaction mixture, and the reaction mixture was extracted with ethyl acetate twice. The combined organic layers were washed with a saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 0.64 g of N-[2-hydroxy-5-(trifluoromethyl)phenyl]-3(methoxymethyl)isonicotinamide.
