실험 절차

Benzylamine (0.69 mL, 6.31 mmol) was added slowly to a mixture of 4-Bromo-2-methoxy-1-benzenecarbonyl chloride (1.5 g, 6.01 mmol) and triethylamine (1.3 mL, 9.02 mmol) in dichloromethane (60 mL). After 3 hours, solvent was removed under reduced pressure. Ethyl acetate was added and the mixture was filtered. The filtrate was concentrated under reduced pressure and the residue was re-crystallized from ethyl acetate/heptane to give N1-benzyl-4-bromo-2-methoxybenzamide (1.654 g, 86%). 1H NMR (DMSO-d6) δ 3.92 (s, 3H), 4.67 (d, J=5.67 Hz, 32H), 7.31 (m, 7H), 8.03 (bs, 1H), 8.13 (d, J=8.41, 1H).
