실험 절차

To a solution of methyl [3,5-bis(trifluoromethyl)benzyl]{[5′-formyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate (Example 73, 184 mg, 0.31 mmol) in anhydrous tetrahydrofuran at 0° C., 0.5 M trimethyl(trifluoromethyl) silane (2.5 mL, 1.24 mmol) and a catalytic amount of tetrabutylammonium fluoride were added. The reaction was stirred with gradual warming to room temperature. Once the reaction was complete, it was quenched with saturated ammonium chloride solution. The organic was extracted with methylene chloride, washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated. The title compound was obtained by preparative thin layer chromatography using 1:4 acetone:hexane. 1H NMR (CDCl3, 600 MHz) δ 7.74 (s, 1H), 7.61 (m, 1H), 7.15-7.56 (m, 6H), 6.99 (m, 1H), 4.97 (m, 1H), 4.19-4.38 (m, 4H), 3.61-3.76 (m, 6H). LC-MS (M+Na) 686.9 (4.28 min).
