실험 절차

To a solution of (1H-Benzimidazol-2-ylmethyl)-(2-Aminomethyl-benzyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amine (see AMD9720) (50 mg, 0.125 mmol) in THF (5 mL) was added N,N′-di-t-butoxycarbonyl-pyrazole-1-carboxamidine (60 mg, 0.187 mmol) and potassium carbonate (35 mg, 0.25 mmol) and the mixture stirred overnight. The reaction was diluted with aqueous NH4Cl (5 mL) and extracted with ethyl acetate (3×10 mL). The combined organic fractions were dried (Na2SO4), concentrated and purified by chromatography on silica gel (5% MeOH/CH2Cl2) to give the desired product as a pale foam (51 mg, 64%). 1H NMR (CDCl3) δ 1.47 (s, 9H), 1.48 (s, 9H), 1.81 (m, 1H), 2.00 (m, 2H), 2.26 (m, 2H), 2.71-2.88 (m, 2H), 3.89-4.05 (m, 5H), 4.73 (dd, 1H, J=15.5, 5.1 Hz), 4.96 (dd, 1H, J=15.5, 5.7 Hz), 7.12 (m, 7H), 7.36-7.44 (m, 3H), 7.55 (br s, 1H (NH)), 8.55 (m, H (NH)), 8.66 (d, 1H, J=5.1 Hz).
