To a mixture 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 (25 mg, 0.040 mmol) in dichloromethane (1 mL) was added diisopropyl ethylamine (0.028 mL, 0.160 mmol) followed by 4-(morpholinosulfonyl)benzene-1-sulfonyl chloride (13.00 mg, 0.040 mmol) and the resulting solution stirred at room temperature for 24 h. The mixture was treated with sodium ethoxide (0.015 mL, 0.040 mmol) and stirred at room temperature for 1 h. The reaction was diluted with water and dichloromethane. The aqueous phase was acidified with 1N HCl and the product extracted into the organic phase. The organic phase was concentrated and the residue was triturated with methanol. The white solids were collected by filtration to give the title compound (2.2 mg, 7% yield).
