実験手順

To a stirred solution of N′-(1H-benzimidazol-2-ylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (0.231 g, 0.58 mmol) in dry MeOH (5.5 mL) was added N-(tert-butoxycarbonyl)-L-prolinal (0.116 g, 0.58 mmol) and the mixture was stirred at room temperature for 2.5 h. The reaction mixture was concentrated under reduced pressure and subjected to high vacuum for 1 h. The residue was dissolved in dry MeOH (5 mL) and to the resultant solution was added sodium borohydride (44 mg, 1.16 mmol), which was stirred for 0.5 h (see General Procedures XX). Purification by radial chromatography on a 2 mm TLC grade silica gel plate (CH2Cl2/MeOH/NH4OH, 100:1:1 followed by 50:1:1) afforded the desired product (0.151 g, 45%) as a colourless oil.
