Procedure

A mixture of 10-chloro-1-(2,4-dichlorophenyl)-7-nitro-2,3,4,5-tetrahydro-1H-[1,3]diazepino[1,2-a]benzimidazole (53 mg, 0.129 mmol) and 10% palladium on carbon (6 mg) in acetic acid (5.0 mL) was stirred under hydrogen atmosphere at room temperature for 6 hr. The catalyst was removed by filtration and the filtrate was concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with a 50-100% ethyl acetate/n-hexane gradient mixture. The filtrate was concentrated in vacuo to give the title compound (32 mg, 0.084 mmol, 65%) as an oil.
