Reaction Steps
Using General Procedure B: 1H-Indole-3-carbaldehyde (73 mg, 0.50 mmol) and N′-(1H-benzimidazol-2-ylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (200 mg, 0.50 mmol) were stirred at 40° C. in MeOH (5 mL) for 4 hours. NaBH4 (38 mg, 1.0 mmol) was added and the resultant mixture stirred at room temperature for an additional 15 minutes. Purification of the crude white foam by column chromatography on silica gel (200:1:1—EtOAc:MeOH:NH4OH) afforded AMD9673 (80 mg, 31%) as a white foam. 1H NMR (CDCl3) δ 1.59–1.75 (m, 1H), 1.81–2.09 (m, 2H), 2.16–2.30 (m, 1H), 2.64–2.76 (m, 1H), 2.76–2.91 (m, 1H), 3.69 (s, 2H), 3.78 (s, 2H), 3.92–3.98 (m, 3H), 4.04–4.09 (m, 1H), 4.15 (d, 1H, J=16.5 Hz), 7.02–7.07 (m, 2H), 7.11–7.21 (m, 6H), 7.25–7.34 (m, 3H), 7.41 (d, 1H, J=7.2 Hz), 7.54–7.57 (m, 3H), 8.68 (d, 1H, J=3.9 Hz), 8.75 (br s, 1H); 13C NMR (CDCl3) δ 21.74, 23.88, 29.60, 44.05, 48.89, 52.95, 54.06, 60.72, 111.68, 113.70, 119.08, 119.77, 121.97, 122.30, 122.66, 123.71, 127.40, 128.84, 129.07, 135.15, 136.70, 137.66, 138.60 (2 carbons), 147.27, 156.70, 157.79. ES-MS m/z 532.4 (M-C9H8N). Anal. Calcd. for C34H34N6.0.7H2O.0.2CH2Cl2: C, 73.84; H, 6.49; N, 15.11. Found: C, 73.95; H, 6.60; N, 14.81.
