Reaction Steps

Using General Procedure B: Reaction of 4-{[(1H-Benzimidazol-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amino]-methyl}-benzaldehyde (AMD9882) (157 mg, 0.40 mmol) and dimethylamine (2.0 M in THF, 0.4 mL, 0.80 mmol) with NaBH(OAc)3 (0.179 g, 0.84 mmol) in CH2Cl2 (4 mL) overnight followed by purification of the crude material by radial chromatography on silica gel (2 mm plate, 50:1:1 CH2Cl2—CH3OH-NH4OH) provided the free base of the title compound (72 mg, 43%) as a colorless oil.
