実験手順

A mixture of 4-Bromophenylacetic acid (1.5 g, 7.0 mmol, 1 eq.), EDC (2.67 g, 14.0 mmol, 2 eq.), DMAP (846 mg, 7.0 mmol, 1 eq.), and phenylamine (0.765 mL, 8.4 mmol, 1.2 eq.) in 15 mL of DMF was stirred under nitrogen at room temperature for 3.5 hrs. After aqueous workup and recrystallization, 2-(4-Bromophenyl)-N-phenyl-acetamide was obtained in 69% yield (1.4 g). 1H NMR (400 MHz, DMSO-D6) δ ppm 3.6 (s, 2 H) 7.0 (m, 1 H) 7.3 (m, 4 H) 7.5 (m, 2 H) 7.6 (dd, J=8.7, 1.1 Hz, 2 H) 10.2 (s, 1 H).
