Procedure

(1R,2S,7R,8S)-3-(4-Fluoro-benzyl)-6-hydroxy-5-(7-iodo-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-3-aza-tricyclo[6.2.1.02,7]undec-5-en-4-one (prepared as described in Example 19, 100 mg, 0.17 mmol), pyridine-3-sulfonic acid amide (81 mg, 0.51 mmol), sarcosine (N-methyl glycine) (23 mg, 0.26 mmol), copper (I) iodide (33 mg, 0.17 mmol), and potassium phosphate (216 mg, 1.02 mmol) were combined and dissolved in N,N-dimethylformamide (10 mL). The flask was degassed and backfilled with nitrogen (3×). The reaction was stirred at 100° C. for 4 h. The mixture was cooled to 25° C., diluted with ethyl acetate (20 mL), and extracted with saturated aqueous sodium bicarbonate solution (2×20 mL). The combined organic layers were dried over magnesium sulfate, filtered, and concentrated in vacuo. Purification by flash column chromatography (Teledyne Isco RediSep column; 0 to 8% methanol in dichloromethane) afforded the desired product, pyridine-3-sulfonic acid {3-[(1R,2S,7R,8S)-3-(4-fluoro-benzyl)-6-hydroxy-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}-amide (56 mg, 0.09 mmol, 54%), as a white powder. 1H NMR (400 MHz, DMSO-d6) δ: 1.38-1.58 (6H, m), 2.61 (1H, s), 3.00 (1H, d, J=7.6 Hz), 3.52 (1H, d, J=8.4 Hz), 4.40 (1H, d, J=15.6 Hz), 4.94 (1H, d, J=15.2 Hz), 7.13 (2H, t, J=8.4 Hz), 7.29-7.32 (2H, m), 7.42-7.50 (3H, m), 7.60-7.63 (1H, m), 8.11 (1H, d, J=7.6 Hz), 8.79 (1H, d, J=4.4 Hz), 8.87 (1H, s), 10.94 (1H, s), 13.99 (1H, s). LC-MS (ESI) calcd for C29H26FN5O6S2 623.68, found 624.2 [M+H+].
