Reaction Steps

To a stirred solution of (3-bromo-4-(2-bromoethoxy)phenyl)(4-methoxyphenyl)methanone (0.6 g, 1.0 e q) in 50 mL CH2Cl2 was added BBr3 (3.0 eq, 0.4 mL) dropwise. After addition, the mixture was stirred at rt overnight, concentrated, and purified by column chromatography with petroleum ether:EtOAc=2:1 to give the desired product (0.36 g, 62% yield). 1H NMR (400 MHz, CDCl3) δ 8.03 (s, 1H), 7.70-7.79 (m, 3H), 6.90-7.00 (m, 3H), 4.43 (t, J=6.4 Hz, 2H), 3.72 (t, J=6.0 Hz, 2H).
