Procedure

To a stirred solution of methyl (1R,2S,3R,4S)-3-[(4-fluorobenzyl)amino]-7-oxabicyclo[2.2.1]heptane-2-carboxylate (0.056 g, 0.21 mmol) in anhydrous N,N-dimethylformamide (3 mL) under a nitrogen atmosphere, (7-methanesulfonylamino-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-acetic acid (prepared as described in Example 1g, 0.070 g, 0.21 mmol) was added followed by N-methylmorpholine (0.046 mL, 0.42 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (40 mg, 0.21 mmol). The mixture was stirred at 25° C. for 1 h, triethylamine (0.88 mL, 0.63 mmol) was added and the resulting mixture was stirred at 50° C. for 16 h. The reaction mixture was allowed to cool to 25° C., diluted with ethyl acetate, washed with 1.0 M aqueous hydrochloric acid solution and saturated aqueous brine solution, dried over magnesium sulfate and filtered. The filtrate was concentrated in vacuo and the residue was purified by prep-HPLC [Column Luna 5μ C18 (2) 100 Å AXIA 150×21.2 mm, 5 micron, 30%-95% in 7 min @ 30 mL/min flow rate, 0.05% trifluoroacetic acid in acetonitrile/0.05% trifluoroacetic acid in water] to afford the desired product, N-{3-[(1S,2R,7S,8R)-3-(4-fluoro-benzyl)-6-hydroxy-4-oxo-11-oxa-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 (48 mg, 0.085 mmol, 41%), as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ: 1.51-1.71 (4H, m), 3.05 (3H, s), 3.30 (1H, m), 3.79 (1H, d, J=8.4 Hz), 4.40 (1H, d, J=15.6 Hz), 4.70 (1H, d, J=4.8 Hz), 4.76 (1H, d, J=4.8 Hz), 5.04 (1H, d, J=14.8 Hz), 7.15 (2H, t, J=8.4 Hz), 7.33 (2H, m), 7.49 (1H, dd, J=8.4, 2.4 Hz), 7.55 (2H, m).
