実験手順

Potassium carbonate (0.067 g, 0.488 mmol) and iodomethane (0.017 mL, 0.268 mmol) were added sequentially to a solution of N-{3-[4-hydroxy-1-(3-methyl-butyl)-2-oxo-2,4a,5,6,7,8,9,9a-octahydro-1H-cyclohepta[b]pyridin-3-yl]-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-7-yl}-methanesulfonamide (prepared as described in Example 33b, 0.128 g, 0.244 mmol) in N,N-dimethylformamide (4 mL) at 25° C. The reaction mixture was stirred at 25° C. for 2 h, and then was partitioned between ethyl acetate (30 mL) and water (2×20 mL). The organic layers were washed with saturated aqueous brine solution (50 mL), dried over sodium sulfate, filtered, and were concentrated in vacuo. The residue was purified by flash column chromatography (Analogix SuperFlash Column; 30-80% ethyl acetate in hexanes) to afford the desired product, N-{3-[4-hydroxy-1-(3-methyl-butyl)-2-oxo-2,4a,5,6,7,8,9,9a-octahydro-1H-cyclohepta[b]pyridin-3-yl]-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-7-yl}-N-methyl-methanesulfonamide (0.045 g, 0.084 mmol, 34%), as a white solid. 1H NMR (400 MHz, CDCl3) δ: 1.00 (d, 6H, J=7.1 Hz), 1.40-2.24 (m, 14H), 2.88 (d, 3H, J=2.1 Hz), 2.94-3.09 (m, 1H), 3.30-3.53 (m, 2H), 3.37 (d, 3H, J=3.1 Hz), 3.95-4.09 (m, 1H), 7.17-7.23 (m, 1H), 7.67-7.73 (m, 1H), 7.77-7.80 (m, 1H). LC-MS (ESI) calcd for C24H34N4O6S2 538.19, found 539.4 [M+H+].
