실험 절차

(1R,2S,7R,8S)—N-{3-[6-Hydroxy-3-(3-methyl-butyl)-4-oxo-3-aza-tricyclo[6.2.1.02,7]undec-5-en-5-yl]-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-7-yl}-methanesulfonamide (prepared as described in Example 22, 90 mg, 0.172 mmol) was dissolved in anhydrous N,N-dimethylformamide (2 mL). Potassium carbonate (0.04 g, 0.344 mmol) was added followed by iodomethane (0.027 g, 0.189 mmol). The mixture was stirred at 25° C. for 5 h. The reaction mixture was extracted with ethyl acetate (2×100 mL) and water (100 mL). The organic layer was washed with saturated aqueous brine solution (50 mL), dried over sodium sulfate and filtered. The filtrate was concentrated in vacuo to afford the crude product, which was purified by flash column chromatography (Teledyne Isco RediSep column; 40% ethyl acetate in hexanes) to afford the desired product, (1R,2S,7R,8S)—N-{3-[6-hydroxy-3-(3-methyl-butyl)-4-oxo-3-aza-tricyclo[6.2.1.02,7]undec-5-en-5-yl]-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-7-yl}-N-methyl-methanesulfonamide (0.052 g, 0.097 mmol, 56.4%), as a white solid. 1H NMR (400 MHz, DMSO-d6) δ: 0.92 (6H, d, J=6.4 Hz), 1.21-1.26 (1H, m), 1.28-1.33 (1H, m), 1.39-1.63 (7H, m), 2.54 (1H, bs), 2.63-2.67 (1H, m), 3.00 (3H, s), 3.06-3.17 (1H, m), 3.29 (3H, s), 3.63-3.72 (2H, m), 7.62 (1H, d, J=8.5 Hz), 7.70-7.73 (1H, m), 7.85 (1H, s). LC-MS (ESI) calcd for C24H32N4O6S2 536.18, found 537.6.6 [M+H+].
