To a solution of (4-bromophenyl)[2-methyl-4-(methyloxy)phenyl]methanone (27) (1.12 g, 3.67 mmoL) in benzene (25 mL) was added AlCl3 (1.98 g, 14.85 mmol). The mixture was heated at 90° C. for 3 h. Upon cooling, water (25 mL) was added, and the mixture was extracted with Et2O. The organics were dried with MgSO4 and concentrated. The crude material was purified by chromatography on silica gel (EtOAc:hexanes) to yield 1.32 g (86%) of compound 28. 1H NMR (400 MHz, DMSO-d6): δ 2.26 (s, 3H), 6.63 (dd, J=2.4 Hz, 8.4 Hz, 1H), 6.72 (d, J=2.2 Hz, 1H), 7.18 (d, J=8.4 Hz, 1H), 7.55 (d, J=8.4 Hz, 2H), 7.70 (d, J=8.4 Hz, 2H), 10.10 (s, 1H).
