Versuchsvorschrift

2-Oxo-3-tert-butoxycarbonylamino-5-(2-cyclohexen-1-yl)-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepine (1.05 g) obtained from Step 1 of Referential Example 10 was dissolved in toluene (14 ml), 2-bromo-2′-methylacetophenone (723 mg), 1N aqueous sodium hydroxide (7 ml) and tetra n-butylammonium bromide (20 mg) were added, and the mixture was stirred overnight at room temperature. The reaction mixture was separated into organic layer and aqueous layer, the organic layer was dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography(n-hexane:ethyl acetate=5:1), to thereby obtain 557 mg of the titled compound.
