실험 절차

Using General Procedure B: To a stirred solution of N-(tert-butoxycarbonyl)-D-prolinal (0.121 g, 0.61 mmol) in dry CH2Cl2 (9 mL) was added N′-(1H-benzimidazol-2-ylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (0.236 g, 0.59 mmol) at room temperature and the mixture stirred for 40 min. To the resultant mixture was added sodium triacetoxyborohydride (0.174 g, 0.82 mmol) and the mixture stirred overnight at room temperature. Purification and separation of the crude material by radial chromatography on a 2 mm TLC grade silica gel plate (CH2Cl2/MeOH/NH4OH, 50:1:1) afforded the more polar mono-alkylated (77 mg, 23%) and the less polar dialkylated (70 mg, 21%) products, both as white foams.
