Using General Procedure B: To a stirred solution of 4-{[(1H-Benzimidazol-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amino]-methyl}-benzaldehyde (199 mg, 0.50 mmol) and 3-aminopyrazole (60 mg, 0.72 mmol) in THF (5 mL) and acetic acid (0.2 mL) was added NaBH(OAc)3 (166 mg, 0.78 mmol) and the resultant mixture stirred at room temperature for 2.5 days. Purification of the crude material by radial chromatography on silica gel gel (2 mm plate, CH2Cl2/MeOH/NH4OH, 100:1:1 then 50:1:1) afforded the desired amine (52 mg, 23%) as a white foam.
