実験手順
A mixture of 5.8 g 3-trifluoromethyl-p-anisaldehyde, 8.6 ml formamide, and 13.6 ml formic acid was stirred at 130° C. for 9 hr. After cooling, water and ethyl acetate were added thereto. The ethyl acetate layer was recovered and washed with brine. It was dried over anhydrous magnesium sulfate, filtered, and evaporated. The resulting residue was purified by silica gel column chromatography to give 3.8 g of N-[4-methoxy-3-(trifluoromethyl)benzyl]formamide.
