Procedure

14.6 g of 5-acetamino-6-nitro-indane were boiled under reflux overnight in 1.5 l of methanol with 300 ml of hydrochloric acid in methanol and then evaporated. 11.8 g of crude product were recrystallized from acetonitrile. There were obtained 10.9 g (92.3% of theory) of 5-amino-6-nitro-indane of melting point 131°-132° C.
