A suspension of N-(4-nitro-2,3-dihydro-1H-inden-5-yl)acetamide (0.90 g, 4.09 mmol) in 5 M HCl was heated at 100° C. for 16 h. The suspension was cooled to 20° C., diluted with water (100 mL), filtered, washed with water (3×15 mL) and dried to give 4-nitro-5-indanamine 3 (Schroeder, E, et al., European J. Med. Chem. 1982, 17, 35) (0.69 g, 95%) as an orange solid: mp (H2O) 105-107° C.; 1H NMR δ 7.17 (d, J=8.2 Hz, 1H, H-7), 6.62 (d, J=8.2 Hz, 1H, H-6), 5.73 (br s, 2H, NH2), 3.32 (br t, J=7.5 Hz, 2H, H-3), 2.80-2.85 (m, 2H, H-1), 2.02-2.11 (m, 2H, H-2).
