Reaction Steps

A suspension of ethyl 2,2-dimethyl-3-(5-(quinolin-2-ylmethoxy)-1H-benzo[d]imidazol-2-yl)propanoate) (300 mg, 0.74 mmol), 1-bromo-4-(1-bromopropyl)benzene (413 mg, 1.49 mmol) and cesium carbonate (727 mg, 2.23 mmol) in DMF (3.7 mL) was heated to 100° C. for 3 days. The mixture was cooled and partitioned between water and EtOAc. The organic layer was dried and concentrated to a residue. Purification using FCC afforded the title compound. MS (ESI): mass calcd. for C33H34BrN3O3, 599.18; m/z found, 600.1 [M+H]+. 1H NMR (400 MHz, CDCl3) δ 8.14 (d, J=8.5, 1H), 8.05 (d, J=8.5, 1H), 7.83 (d, J=8.2, 1H), 7.74 (ddd, J=8.4, 6.9, 1.4, 1H), 7.62-7.53 (m, 3H), 7.28-7.25 (m, 2H), 6.97-6.92 (m, 3H), 6.62 (d, J=2.3, 1H), 5.38 (dd, J=10.0, 5.9, 1H), 5.34-5.22 (m, 2H), 4.05 (qd, J=7.1, 0.8, 2H), 3.08 (q, J=15.6, 2H), 2.42-2.23 (m, 2H), 1.37 (s, 3H), 1.35 (s, 3H), 1.15 (t, J=7.1, 3H), 0.72 (t, J=7.3, 3H).
