Procedure

The crude rac-Methyl (1R,2R,4S,5S,6R,7S)-7-{[(4-fluorophenyl)methyl]amino}tricyclo[3.2.2.02,4]nonane-6-carboxylate was dissolved in anhydrous N,N-dimethylformamide (8 mL). (7-Methanesulfonylamino-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-acetic acid (prepared as described in Example 1g, 0.22 g, 0.66 mmol) was added followed by N-methylmorpholine (0.15 mL, 1.39 mmol). The mixture was stirred until everything dissolved, approximately 5 min. 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.13 g, 0.69 mmol) was added and the mixture was stirred at 25° C. for 4 h. Triethylamine (0.28 mL, 1.98 mmol) was added and the mixture was stirred at 50° C. for 16 h. Upon cooling to 25° C., the solution was diluted with ethyl acetate (50 mL) and washed with 1.0M aqueous hydrochloric acid solution (2×50 mL), saturated aqueous brine solution (20 mL), dried over magnesium sulfate, filtered, and concentrated in vacuo to afford a golden oil. Purification by flash column chromatography (Teledyne Isco RediSep column; 0 to 20% ethyl acetate in dichloromethane) afforded the desired product, rac-N-{3-[(1R,2S,7R,8S,9S,11R)-3-[(4-Fluorophenyl)methyl]-6-hydroxy-4-oxo-3-azatetracyclo[6.3.2.02,7.09,11]trideca-5-en-5-yl]-1,1-dioxo-4H-1λ6,2,4-benzothiadiazin-7-yl}methanesulfonamide (0.50 g, 0.86 mmol, 80% over three steps), as a white powder. 1H NMR (400 MHz, DMSO-d6) δ: 0.33-1.34 (10H, m), 2.30 (1H, bs), 3.06 (3H, s), 3.81 (1H, d, J=11.2 Hz), 4.48 (1H, d, J=15.6 Hz), 4.98 (1H, d, J=14.8 Hz), 7.13-7.60 (7H, m), 10.19 (1H, s). LC-MS (ESI) calcd for C27H27FN4O6S2 586.65, found 587.3 [M+H+].
