Reaction Steps

A mixture of (2-imidazol-1-yl-ethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amine (92 mg, 0.37 mmol), 2-chloromethyl-benzimidazole-1-carboxylic acid tert-butyl ester (101 mg, 0.379 mmol), potassium iodide (3 mg, 0.02 mmol), and N,N-diisopropylethylamine (0.10 mL, 0.57 mmol) in acetonitrile (4 mL) was heated at 60° C. for 15 h. Saturated NaHCO3(aq) (15 mL) was added, and the mixture was extracted with CH2Cl2 (3×15 mL). The combined organic extracts were dried (MgSO4) and concentrated in vacuo. Purification of the crude material by column chromatography on silica gel (250:5:1 CH2Cl2/MeOH/NH4OH) gave a yellow oil (21 mg, 12%). 1H NMR (CDCl3) δ 1.45 (m, 1H), 1.66 (m, 10H), 1.91 (m, 2H), 2.69 (m, 2H), 2.92 (m, 1H), 3.18 (m, 1H), 3.67 (m, 2H), 4.20 (dd, 1H, J=10, 5.6 Hz), 4.67 (d, 1H, J=15 Hz), 4.80 (d, 1H, J=15 Hz), 6.74 (s, 1H), 6.90 (s, 1H), 7.01 (dd, 1H, J=7.7, 4.7 Hz), 7.33 (m, 4H), 7.73 (m, 1H), 7.86 (m, 1H), 8.38 (d, 1H, J=3.3 Hz).
