Reaction Steps

To a solution of 3-benzyl 1-methyl 4-(4-(dibutylcarbamoyl)-1H-imidazol-2-yl)isophthalate (275 mg, 0.56 mmol) in dry MeCN (8.0 mL) was added cesium carbonate (182 mg, 0.56 mmol) and 1-bromo-2-chloroethane (80 mg, 0.56 mmol). The reaction mixture was heated at 50° C. for 10 h, diluted with water and extracted with EtOAc (3×). The combined organic layers were dried over Na2SO4 and concentrated in vacuo to give the crude product. The crude material was purified by flash chromatography (gradient from 0% to 2% MeOH/CH2Cl2) to provide the title compound (170 mg, 54%). 1H NMR (DMSO-d6) δ 8.46 (d, J=1.6 Hz, 1H), 8.26 (dd, J=8.0, 1.6 Hz, 1H), 7.85 (s, 1H), 7.75 (d, J=8.0 Hz, 1H), 7.36-7.33 (m, 3H), 7.27-7.25 (m, 2H), 5.16 (s, 2H), 4.08-4.03 (m, 4H), 3.93 (s, 1.5H), 3.77-3.73 (m, 3.5H), 3.50-3.40 (m, 2H), 1.50-1.45 (m, 4H), 1.35-1.10 (m, 4H), 0.92-0.75 (m, 6H); MS(ESI+) m/z 555.0 (M+H)+.
