Reaction Steps

2,4-Difluoro-1-(2-{4-[(2-fluorophenyl)sulfonyl]phenyl}ethyl)benzene (Example 124, 100 mg, 0.26 mmol), potassium carbonate (126 mg, 0.39 mmol) and imidazole (26 mg, 0.39 mmol) were combined in dimethylsulfoxide (1.3 mL) and heated in a microwave reactor at 150° C. for 20 minutes. The reaction mixture was diluted with ethyl acetate, washed with water and brine, dried over Na2SO4 and evaporated in vacuo. The residue was purified by flash column chromatography on silica, eluting with 5% ethanol/ethyl acetate to yield the title compound as a white solid (85 mg, 77%). δH (400 MHz, d6 DMSO): 8.31-8.29 (1H, m), 7.87-7.79 (2H, m), 7.41-7.39 (2H, m), 7.31-7.23 (5H, m), 7.16-7.12 (1H, m), 6.99-6.95 (1H, m), 6.88 (1H, t, J=1.1 Hz), 6.85 (1H, t, J=1.3 Hz), 2.92-2.84 (4H, m). m/z (ES+) 425 [MH+].
