実験手順

A mixture of 0.51 g of 3-amino-2-hydroxy-5-trifluoromethylpyridine, 0.48 g of 3-methoxymethyl isonicotinic acid, 1.65 g of BOP reagent, 0.38 g of triethylamine and 6 ml of DMF was stirred at room temperature for one hour, and further stirred while heating at 50° C. for two hours. Water was added to the reaction mixture, followed by extraction 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 0.58 g of N-[2-hydroxy-5-(trifluoromethyl)pyridin-3-yl]-3-(methoxymethyl)isonicotinamide.
