Procedure

To a solution of 4-(trifluoromethyl)nicotinic acid (2.11 g, 11.04 mmol) and N,O-dimethylhydroxylamine hydrochloride (1.077 g, 11.04 mmol) in DCM (20 mL) was added N-ethyl-N-isopropylpropan-2-amine (3.78 mL, 22.08 mmol), and HATU (4.20 g, 11.04 mmol). The reaction was stirred at rt under N2 for 5 h. The reaction was then diluted with H2O (50 mL) and extracted with DCM (2×50 mL). The organic layers were combined, dried (MgSO4), and concentrated to give the amide. Purification by ISCO (80 g SiO2, 10-50% EtOAc/hexanes) gives N-methoxy-N-methyl-4-(trifluoromethyl)nicotinamide as a yellow oil.
