Procedure

To a solution of 4-bromobenzoyl chloride (1.04 g, 4.74 mmol) and o-cresol (0.58 g, 5.33 mmol) in CH2Cl2 (20 mL) was added AlCl3 (0.76 g, 5.72 mmol) portion-wise. The mixture was allowed to warm to RT over 12 h. Water was added, and the mixture was extracted with CH2Cl2. The organics were dried with MgSO4 and concentrated. The crude material was purified by chromatography on silica gel (EtOAc:hexanes) to yield 0.21 g (15%) of compound 32. 1H NMR (400 MHz, DMSO-d6): δ 2.15 (s, 3H), 6.89 (d, J=8.3 Hz, 1H), 7.46 (dd, J=2.2 Hz, 8.4 Hz, 1H), 7.54 (d, J=1.9 Hz, 1H), 7.58 (d, 2H), 7.72 (d, 2H), 10.42 (s, 1H).
