実験手順

Using General Procedure B: To a solution of 2-aminobenzylamine (0.36 g, 2.9 mmol) and 6,7-dihydro-5H-quinolin-8-one (0.43 g, 2.9 mmol) in CH2Cl2 (15 mL) was added NaBH(OAc)3 (0.92 g, 4.4 mmol) and the mixture stirred at room temperature for 64 h. Purification of the crude material by column chromatography on silica gel (2% MeOH/CH2Cl2) gave (5,6,7,8-tetrahydroquinolin-8-yl)-(2-aminobenzyl)-amine (0.39 g, 52%) as a yellow oil. 1H NMR (CDCl3) δ 1.80 (m, 1H), 1.94 (m, 2H), 2.17 (m, 1H), 2.79 (m, 2H), 3.84 (m, 1H), 3.87 (d, 1H, J=11.7 Hz), 4.02 (d, 1H, J=12.0 Hz), 6.64 (d, 1H, J=7.8 Hz), 6.67 (t, 1H, J=7.8 Hz), 7.09 (m, 3H), 7.38 (d, 1H, J=3.0 Hz), 8.38 (d, 1H, J=3.9 Hz).
