Procedure

According to the general procedure A, 2-bromotoluene (188 mg, 1.10 mmol) reacted with diphenylamine (169 mg, 1.00 mmol) to give the title compound (258 mg, 99%) as a white solid at room temperature for 4 h. Reaction of 2-chlorotoluene (70 mg, 0.55 mmol) with diphenylamine (85 mg, 0.50 mmol) proceeded at 80° C. for 21 h to give the title compound (134 mg, 99%). 1H-NMR (400 MHz, CDCl3): δ 7.14-7.27 (m, 8H), 7.01-6.92 (m, 6H), 2.06 (s, 3H). 13C{1H}-NMR (100 MHz, CDCl3): δ 147.46, 145.37, 136.49, 131.67, 129.61, 128.99, 127.33, 125.95, 121.50, 121.33, 18.56. GC/MS(EI): m/z 259 (M+).
