実験手順

N-BOC-chloromethylbenzimidazole (115 mg, 0.43 mmol), N-Pyridin-2-yl-4-[(5,6,7,8-tetrahydro-quinolin-8-ylamino)-methyl]-benzamide (AMD9362) (155 mg, 0.43 mmol), and K2CO3 (179 mg, 1.29 mmol) were heated to reflux in CH3CN (3 mL) for 24 hours under N2. The reaction mixture was diluted with 200 mL ethyl acetate, and washed with sat. NaHCO3, brine and dried over Na2SO4. Evaporation of the solvent and purification of the residue by flash chromatography on silica gel, followed by radial chromatography on silica gel (2 mm plate, 3:3:94 CH3OH—NH3 H2O—CH2Cl2), afforded AMD9370 (100 mg, 47%) as white foam. 1H NMR (CDCl3) δ 1.68-1.75 (m, 1H), 1.97-2.08 (m, 2H), 2.26-2.32 (m, 1H), 2.71-2.84 (m, 1H), 2.86-2.91 (m, 1H), 3.84 (s, 2H), 3.95 (d, 1H, J=16.5 Hz), 4.08-4.14 (m, 1H), 4.22 (d, 1H, J=16.0 Hz), 7.03-7.07 (m, 1H), 7.16-7.22 (m, 3H), 7.45 (d, 1H, J=6.9 Hz), 7.52-7.61 (m, 3H), 7.65 (d, 1H, J=7.5 Hz), 7.73 (ddd, 1H, J=1.8, 7.2, 8.7 Hz), 7.80 (d, 2H, J=8.1 Hz), 8.27-8.29 (m, 1H), 8.33 (d 1H, J=8.4 Hz), 8.44 (br, s, 1H), 8.72-8.80 (m, 1H); 13C NMR (CDCl3) δ 21.72, 23.30, 29.56, 49.29, 54.16, 60.83, 111.39, 114.52, 120.17, 122.29, 122.81, 127.72, 129.28, 133.58, 135.17, 137.76, 138.77, 144.61, 147.38, 148.21, 152.00, 156.13, 157.54, 165.99; ES-MS m/z 489.2 (M+H); Anal. Calcd. for (C30 H28N6O)•0.6(H2O)•0.7(CHCl3): C, 63.25; H, 5.17; N, 14.42. Found: C, 63.56; H, 5.25; N, 14.31.
