To N-(5-nitro-indan-2-yl)-acetamide (23.5 g, 107 mmol) is added 2N hydrochloric acid (500 mL). The mixture is heated to reflux for 24 h and then concentrated in vacuo. Methanol (100 mL) is added to the residue and the mixture is concentrated in vacuo. Toluene (100 mL) is added and the mixture is again concentrated. A solution of the residue in methanol (100 mL) is warmed, diethyl ether (500 mL) is added and the mixture is let stand overnight. The solid is collected by filtration and air dried to yield 2-amino-5-nitroindane hydrochloride as a white solid.
