Procedure

10-bromo-3-(3-cyclopropyl-1H-1,2,4-triazol-5-yl)-9-fluoro-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide was prepared similarly according to Procedure I. Cyclopropylcarboxamidine hydrochloride was reacted with 10-bromo-9-fluoro-3-iodo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide then hydrazine. The completed reaction was then diluted with methylene chloride and filtered over celite to afford 334 mg (70% yield) of the title compound.
