Reaction Steps

Phenethylamine (1.2 mL, 9.57 mmol) was added slowly to a mixture of 4-Bromo-1-benzenecarbonyl chloride (2.0 g, 9.11 mmol) and triethyl amine (1.9 mL, 13.67 mmol) in dichloromethane (95 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-phenyl-4-bromobenzamide (1.925 g, 69%). 1H NMR (DMSO-d6) δ 2.84 (m, 2H), 3.47 (m, 2H), 7.28 (m, 5H), 7.67 (d, J=8.59 Hz, 2H), 7.76 (d, J=8.59 Hz, 4H), 8.64 (m, 1H).
