Reaction Steps

A mixture of 6-[10-chloro-7-(1-ethylpropyl)-2,3,4,5-tetrahydro-1H-[1,3]diazepino[1,2-a]benzimidazol-1-yl]-5-methylpyridine-3-carbonitrile (100 mg, 0.245 mmol) and potassium hydroxide (41 mg, 0.735 mmol) in tert-butanol (2 mL) was stirred at 800° C. for 2 hr. After cooling, water was added and the mixture was extracted with ethyl acetate. Organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was recrystallized from ethyl acetate/isopropyl ether to afford the title compound (70 mg, 67%) as a colorless solid.
