実験手順

Phenyl isocyanate (110 mg) was added to a solution of 1-tert-butylcarbonylmethyl-2-oxo-3-amino-5-cyclohexyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepine (300 mg) in anhydrous tetrahydrofuran (10 ml), the mixture was stirred for 10 minutes at room temperature. The reaction mixture was concentrated under reduced pressure, etanol was added to the residue for crystallization, collected by filtration, to thereby obtain 336 mg of the title compound (Yield 83.9%).
