実験手順

To a mixture of 4-(adamantan-1-ylmethoxy)-N-(azetidin-1-ylsulfonyl)-2-fluoro-5-iodobenzamide (0.20 g, 0.36 mmol) in anhydrous tetrahydrofuran (5 mL) was added isopropylmagnesium chloride lithium chloride complex (1.3 M solution in tetrahydrofuran, 0.69 mL, 0.90 mmol) at −40° C. After 1 hour at −40° C., additional isopropylmagnesium chloride lithium chloride complex (1.3 M solution in tetrahydrofuran, 0.28 mL, 0.36 mmol) was added, the reaction mixture warmed to 0° C., and stirred for 1 hour. Cyclopropanecarboxaldehyde (excess) was then added, the reaction mixture was allowed to warm to ambient temperature, and stirred for 16 hours. After quenched with 1 N hydrochloric acid (3 mL), the mixture was diluted with ethyl acetate (50 mL). The combined organic phase was washed with brine (5 mL), dried over anhydrous sodium sulfate, and filtered. Concentration of the filtrate in vacuo gave a residue which was purified by reverse-phase preparative HPLC to afford the title compound as a colorless solid (0.015 g, 8%): 1H NMR (300 MHz, DMSO-d6) δ 11.69 (br s, 1H), 7.73 (d, J=8.7 Hz, 1H), 6.91 (d, J=12.7 Hz, 1H), 5.14 (d, J=4.5 Hz, 1H), 4.61 (dd, J=5.7, 4.9 Hz, 1H), 4.02-3.90 (m, 4H), 3.66 (d, J=9.3 Hz, 1H), 3.56 (d, J=9.3 Hz, 1H), 2.19-2.06 (m, 2H), 2.03-1.95 (m, 3H), 1.76-1.57 (m, 12H), 1.18-1.05 (m, 1H), 0.40-0.25 (m, 4H); MS (ES−) m/z 491.2 (M−1).
