Procedure

Using General Procedure A: To a stirred solution of 4-{[(1H-benzimidazol-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amino]-methyl}-benzaldehyde (200 mg, 0.49 mmol) and the amine (41 mg, 0.49 mmol) from above in MeOH (5 mL) was added NaBH3CN (94.3 mg, 1.5 mmol) and the mixture was stirred at room temperature for 5 days. Purification of the crude yellow foam by column chromatography on silica gel (100:1:1—CH2Cl2:MeOH:NH4OH) afforded AMD9741 (26 mg, 15%) as a brown solid (22mg, 10%). 1H NMR (CDCl3) δ 1.61-1.76 (m, 1H), 1.92-2.09 (m, 2H), 2.17-2.27 (m, 1H), 2.68-2.76 (m, 1H), 2.80-2.90 (m, 1H), 3.64 (s, 2H), 3.89 (d, 1H, J=16.5 Hz), 4.05-4.14 (m, 2H), 4.22 (s, 2H), 4.39 (br s, 1H), 6.54 (s, 2H), 7.06 (d, 2H, J=7.8 Hz), 7.15-7.20 (m, 3H), 7.25 (d, 2H, J=6.9 Hz), 7.43 (d, 1H, J=7.8 Hz), 7.54 (br s, 2H), 8.67 (d, 1H, J=4.5 Hz); 13C NMR (CDCl3) δ 19.22, 21.83, 27.12, 45.73, 46.41, 51.49, 58.49, 111.83, 112.90, 115.59, 119.64, 120.29, 125.33, 126.71, 132.76, 135.33, 135.86, 136.22, 144.75, 148.75, 154.19, 155.23.
