実験手順

Methylmagnesium bromide (0.59 mL, 0.83 mmol) was added dropwise to a solution of methyl [3,5-bis(trifluoromethyl)benzyl]{[5′-formyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate (Example 73, 289 mg, 0.49 mmol) in anhydrous tetrahydrofuran at 0° C. The solution was allowed to warm to room temperature. Once the reaction was complete, saturated ammonium chloride solution was added to quench the reaction. The mixture was extracted with methylene chloride, washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated. The title compound was obtained by flash chromatography using 30% acetone/hexane. 1HNMR (CDCl3, 600 MHz) δ 7.73 (s, 1H), 7.58 (m, 1H), 7.32-7.51 (m, 5H), 7.11 (m, 1H), 6.94 (m, 1H), 4.87 (m, 1H), 4.25-4.43 (m, 4H), 3.69 (m, 6H), 1.48 (d, J=4.2 Hz, 3H). LC-MS (M+Na) 632.0 (4.18 min).
