실험 절차
A suspension of 1-[3-(4-fluorophenyl)-1-(tetrahydropyran-2-yl)-1H-indazol-5-yl]-2-phenylethan-1-ol (0.223 g, 0.54 mmol) and pyridinium chlorochromate (1.0 g, 4.6 mmol) in dried dichloromethane (10 mL) under nitrogen was stirred at ambient temperature for 6 hours. It was diluted with dichloromethane and washed with saturated sodium bicarbonate and brine. The organic layer was dried over magnesium sulfate, filtered, and concentrated. The residue was then purified by chromatography (SiO2, 15-30% ethyl acetate/hexane) to provide the title compound (0.112 g, 51% yield): 1H NMR (CDCl3) δ 8.62 (d, 1H), 8.10 (dd, 1H), 7.85-7.90 (m, 2H), 7.65 (dd, 1H), 7.19-7.37 (m, 7H), 5.77 (dd, 1H), 4.35 (s, 2H), 4.06 (m, 1H), 3.77 (m, 1H), 2.59 (m, 1H), 2.14 (m, 2H), 1.70 (m, 3H); ES-MS (m/z) 415 [M+1]+.
