Procedure
To a suspension of N-(4-fluorobenzyl)-3-hydroxy-4-oxo-10-((oxo(1-piperazinyl)acetyl)amino)-4,6,7,8,9,10-hexahydro-7,10-ethanopyrimido[1,2-a]azepine-2-carboxamide (0.025 g, 0.040 mmol) in dichloromethane (1 mL) was added diisopropyl ethylamine (0.028 mL, 0.160 mmol) and the solution was stirred at room temperature for 5 min. Added to this was dimethylsulfamoyl chloride (4.26 μL, 0.040 mmol) and the solution was stirred at room temperature for 16 h. The reaction solution was concentrated and purified by preparative HPLC: Solvent A=10% methanol/90% H2O/0-1% trifluoroacetic acid; Solvent B=90% methanol/10% H2O/0.1% trifluoroacetic acid; Start % B=20; Final % B=100; Gradient time=20 min; Stop time=30 min; Column=XTERRA® 19×50 mm, C18, 5 μm to give the title compound as a white solid (12.2 mg, 45% yield). LCMS (M+H) calcd for C27H35FN7O7S: 620.23; found: 620.74. 1H NMR (500 MHz, CDCl3) δ: 12.00 (1 H, s), 8.45 (1 H, s), 8.39 (1 H, t, J=5.95 Hz), 7.36 (2H, dd, J=8.55, 5.49 Hz), 7.01 (2 H, t, J=8.55 Hz), 4.55 (2 H, d, J=6.10 Hz), 4.16 (2 H, d, J=3.66 Hz), 4.02-4.09 (2 H, m), 3.52-3.61 (2 H, m), 3.26-3.36 (2 H, m), 3.18-3.26 (2 H, m), 2.84 (6 H, s), 2.58 (2 H, ddd, J=14.19, 9.16, 5.65 Hz), 2.50 (1H, brs), 1.86-2.11 (4 H, m), 1.66-1.80 (2 H, m).
