実験手順

A mixture of 1-(2,4-dichlorophenyl)-7-(diethylamino)-2,3,4,5-tetrahydro-1H-[1,3]diazepino[1,2-a]benzimidazol-4-ol (Example 70; 60.0 mg, 0.143 mmol), tetra-n-propylammonium perruthenate (5.0 mg, 0.014 mmol), 4-methylmorphorine N-oxide (41.9 mg, 0.358 mmol), molecular sieves 4A (60 mg) and acetonitrile (1.5 mL) was stirred at room temperature for 2 hr. The reaction mixture was diluted with water, filtered and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel eluting with a 10-30% ethyl acetate/n-hexane gradient mixture and recrystallization from ethyl acetate/n-hexane to give the title compound as a solid (26.5 mg, 0.0635 mmol, 44%).
