実験手順

The crude (1,1-dioxo-1,4-dihydro-1λ6-thia-2,4,8-triaza-naphthalen-3-yl)-acetic acid sodium salt (˜0.928 mmol), (1S,2R,3S,4R)-3-(4-fluoro-benzylamino)-bicyclo[2.2.1]heptane-2-carboxylic acid ethyl ester (0.27 g, 0.928 mmol) and 047-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (0.494 g, 1.3 mmol) were combined and dissolved in anhydrous N,N-dimethylformamide (2 mL). The mixture was stirred at 25° C. for 1.5 h. Triethylamine (0.697 mL, 5 mmol) was added and the mixture was stirred at 50° C. for 16 h. Upon cooling, the mixture was diluted with ethyl acetate (100 mL), washed with saturated aqueous ammonium chloride solution (2×25 mL) and saturated aqueous brine solution (25 mL). The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo. The resulting solid was triturated with ethyl acetate (˜15 mL) and the product solidified. The solid was collected by vacuum filtration and dried in vacuo for 16 h to afford the desired product, (1R,2S,7R,8S)-5-(1,1-dioxo-1,4-dihydro-1λ6-thia-2,4,8-triaza-naphthalen-3-yl)-3-(4-fluoro-benzyl)-6-hydroxy-3-aza-tricyclo[6.2.1.02,7]undec-5-en-4-one (0.03 g, 0.064 mmol, 6.9%), as a white powder. 1H NMR (400 MHz, DMSO-d6) δ: 0.92-1.05 (2H, m), 1.18-1.46 (4H, m), 2.26 (1H, d, J=3.1 Hz), 2.36 (1H, d, J=9.5 Hz), 2.45 (1H, d, J=3.0 Hz), 3.15 (1H, d, J=9.4 Hz), 4.13 (1H, d, J=15.6 Hz), 4.86 (1H, d, J=15.6 Hz), 7.01-7.05 (2H, m), 7.16-7.20 (2H, m), 7.39-7.42 (1H, m), 7.50 (1H, dd, J1=8.6 Hz, J2=1.6 Hz), 8.26 (1H, dd, J1=4.6 Hz, J2=1.5 Hz). LC-MS (ESI) calcd for C23H21FN4O4S 468.13, found 469.2 [M+H+].
