실험 절차

2-Oxo-3-tert-butoxycarbonylamino-5-cyclohexylcarbonyl-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepine (2.00 g) was suspended in toluene (28 ml), 2-bromo-2′-methylacetophenone (1.28 g), 1N aqueous sodium hydroxide (14 ml) and tetra n-butylammonium bromide (20 mg) were added, and the mixture was stirred for 2 hours at room temperature. The reaction mixture was acidified with 1N hydrochloric acid, extracted with ethyl acetate. The organic layer was successively washed with saturated aqueous sodium bicarbonate and saturated brine, dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure, and diisopropyl was added to the residue for trituration, collected by filtration, to thereby obtain 2.15 g of the titled compound (Yield: 80.7%).
