87% | With ammonium chloride In ethanol at 90℃; for 1 h; | EXAMPLE 129B 6-amino-1-indanone [0367] A solution of Example 129A (19.68 g, 111 mmol) in ethanol (111 mL) was treated sequentially with iron powder (43.0 g, 770 mmol) and solid ammonium chloride (3.70 g, 69.2 mmol). The resulting suspension was stirred at 90° C. for 1 hour, cooled to room temperature, diluted with brine, and extracted with diethyl ether (4.x.100 mL). The combined organic layers were dried (MgSO4), filtered, and concentrated to provide the desired product as a 6:1 mixture of 6-amino- and 4-amino-1-indanone (14.20 g, 87percent). 1H NMR (300 MHz, DMSO-d6, 6-amino-1-indanone) δ 7.21 (d, 1H), 6.92 (dd, 1H), 6.75 (d, 1H), 5.27 (br s, 2H), 2.90 (t, 2H), 2.54 (m, 2H); 1H NMR (300 MHz, DMSO-d6), 4-amino-1-indanone) δ 7.10 (t, 1H), 6.81 (m, 2H), 2.80 (m, 2H), 2.59 (m, 2H). |
