Reaction Steps

To a solution of 4-phenoxybenzoic acid (640 mg, 3 mmol) in anhydrous dichloromethane (30 mL) were added 1H-benzo[d][1,2,3]triazol-1-ol (600 mg, 4.5 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (864 mg, 4.5 mmol) and triethylamine (1.1 g, 10 mmol). After stirring at room temperature for 0.5 hour, (2-methoxy-6-methyl-4-(trifluoromethyl)pyridin-3-yl)methanamine (0.47 g, 2.1 mmol) was added. After stirring at room temperature for 4 hours, to the mixture was added water (20 mL). The resultant mixture was extracted with dichloromethane (20 mL×2). Organic layers were combined and concentrated to give a residue. The residue was purified by chromatography (petroleum ether/ethyl acetate=1:1) to give N-((2-methoxy-6-methyl-4-(trifluoromethyl)pyridin-3-yl)methyl)-4-phenoxybenzamide (600 mg, 67.5%). LRMS (M+H) m/z: calcd 416.13. found 416. 1H NMR (300 MHz, CD3OD): δ 7.78 (d, J=8.7 Hz, 2H), 7.40 (t, J=7.8 Hz, 2H), 7.18 (t, J=7.2 Hz, 1H), 7.12 (s, 1H), 7.05 (d, J=8.1 Hz, 2H), 6.97 (d, J=8.7 Hz, 2H), 4.63 (s, 2H), 4.01 (s, 3H), 2.53 (s, 3H).
