A 4N-hydrogen chloride ethyl acetate solution(6 ml) was added to an ethyl acetate solution (20 ml) of [2-(1-ethyl-3,3,5-trimethyl-2,4-dioxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepine-7-yl)ethyl]carbamic acid tert-butyl ester(0.38 g), and the mixture was stirred at room temperature overnight. The reaction mixture was condensed under reduced pressure to give the title compound(0.26 g) as a pale orange amorphous solid.
