実験手順
A solution of N-(5-nitro-indan-2-yl)-acetamide (Bigge, C. F.; Retz, D. M. WO 9617832 A1) (0.37 g, 1.68 mmol) in ethanol (10 mL) is degassed and 10% palladium on carbon added (0.05 g). The reaction mixture is evacuated and placed under 1 atm H2(g) for 2 h. Fitration of the reaction mixture through Celite is followed by concentration of the filtrate under reduced pressure to give N-(5-amino-indan-2-yl)-acetamide as a white solid which is used directly without further purification. 1H NMR (DMSO-d6, 300 MHz) δ 8.05 (1H, d), 6.82 (1H, d), 6.40 (1H, s), 6.35 (1H, d), 4.81 (2H, bs), 4.38 (1H, m), 2.98 (2H, m), 2.58 (2H, m), 1.81 (3H, s).
