실험 절차
A solution of 2-cyano-5-nitroindane (11.90 g, 63.3 mmol) in methanol/dichloromethane=1:1 (200 ml) was hydrogenated over 10% palladium on charcoal (1.2 g) at 30 p.s.i and 20° C. for 5 hours. The catalyst was filtered off and the filtrate was concentrated under reduced pressure to give 5-amino-2-cyanoindane (10.4 g) which was used directly for the next reaction. A portion, recrystallised from ethanol, formed pinkish needles, m.p. 73°-76° C.
