실험 절차
MnO2 (21.61 g, 249 mmol) was added to a solution of bis(3-bromophenyl)methanol (8.4 g, 24.5 mmol) in dichloromethane (80 mL). The mixture was stirred at 25° C. for 12 h and then filtered. The filter cake was washed with dichloromethane (60 mL×5). The filtrate was concentrated to afford 7.6 g of the title compound (22.3 mmol, 90%). LC/MS: [M+1]=341. 1H NMR (DMSO-d6), 400 MHz: δ 7.52-7.56 (m, 2H), 7.71 (d, 2H, J=7.2 Hz), 7.88-7.92 (m, 4H).
