실험 절차

A mixture of 5-[10-chloro-7-(1-ethylpropyl)-2,3,4,5-tetrahydro-1H-[1,3]diazepino[1,2-a]benzimidazol-1-yl]-4-methylpyridine-2-carbonitrile (Example 59; 70.0 mg, 0.172 mmol), potassium hydroxide (38.5 mg, 0.687 mmol) and t-butyl alcohol (2 mL) was stirred at 80° C. for 15 min. After the reaction mixture was diluted with water at 0° C., the precipitate was collected by filtration and washed with water and diisopropyl ether to give the title compound as a solid (64.8 mg, 0.152 mmol, 88%). Analytically pure material was obtained by recrystallization from ethyl acetate/n-hexane.
