실험 절차

The catalytic hydrogenation procedure of Example 1 was repeated except that the phenyl isocyanate used therein was replaced by 1.7 g. (0.01 mole) of 1-naphthylisocyanate. Reduction was complete in 45 minutes. The catalyst was removed by filtration and the colorless filtrate then evaporated to dryness giving 1.71 g. of tan-white crude product, m.p. 134° - 135° C. The solid was recrystallized from ethanol-water to give 1.62 g. (94% yield) of dried title product, m.p. 137.5° - 138.5° C.
