反应详情

To a 100 mL round-bottomed flask was added 2-(2-methoxyphenyl)ethylamine (1510 mg, 10 mmol, Aldrich), pyridine (10 mL), 4-(trifluoromethyl)benzoyl chloride (2 mL, 10 mmol, Fluka). The reaction mixture was stirred at RT for 1 h. The reaction mixture was diluted with water (20 mL) and extracted with EtOAc (2×50 mL). The organic extract was washed with saturated NaHCO3 (20 mL), saturated NaCl (20 mL), dried over Na2SO4, filtered and concentrated in vacuo and the residue was purified by silica gel chromatography, eluting with 20% EtOAc/CH2Cl2 to give N-(2-methoxyphenethyl)-4-(trifluoromethyl)benzamide. MS (ESI pos. ion) m/z: 324 (M+1).
