Reaction Conditions

Reaction Steps

A mixture of 0.62 g of 2-amino-4-(trifluoromethyl)phenol, 0.48 g of 3-methyl isonicotinic acid, 0.86 g of WSC and 5 ml of pyridine was stirred while heating at 60° C. for three hours. The reaction mixture was cooled to room temperature, and then the reaction mixture was concentrated. Water was poured into the residue, followed by extraction with ethyl acetate. The organic layer was washed with water and a saturated sodium chloride solution, sequentially. The organic layer was dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue was washed with a mixture solvent of tert-butyl methyl ether and hexane to give 0.38 g of N-[2-hydroxy-5-(trifluoromethyl)phenyl]-3-methylisonicotinamide.
