Reaction Steps
To a solution (20 ml) of 4-[5-(4-trifluoromethylphenyl)-2-furyl]benzoic acid -(0.665 g) and N,N-dimethylformamide (0.1 ml) in tetrahydrofuran was added oxalyl chloride (0.209 ml) at 0° C. This mixture was stirred for 10 min., and concentrated. The residue was dissolved in acetonitrile (30 ml), and this solution was added dropwise to 25% aqueous ammonia (50 ml) at 0° C. The mixture was stirred for 10 min. and poured into water. The crystals were collected by filtration and recrystallized from ethanol to give 4-[5-(4-trifluoromethylphenyl)-2-furyl]benzamide (0.506 g, yield 76%) as a colorless crystalline powder. melting point: 263–264° C.
