실험 절차

A solution of 3-amino-2,3,4,5-tetrahydro-1H[1]benzazepin-2-one (4.0 g), 2-t-butyloxycarbonyloxyimino-2-phenylacetonitrile (6.1 g) and triethylamine (5 ml) in water (20 ml) and dioxane (25 ml) was stirred at room temperature for 18 hours. The resulting solid was filtered off and washed with water. Recrystallization from ethyl acetate gave 3-t-butyloxycarbonylamino-2,3,4,5-tetrahydro-1H-[1]benzazepin-2-one, m.p. 199°-201°.
