実験手順

To a stirred solution of methyl 4-(4-(dibutylcarbamoyl)-1H-imidazol-2-yl)-3-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzoate (200 mg, 0.38 mmol) in DMF (8 mL) was added K2CO3 (107 mg, 0.77 mmol) and 3-bromopropanol (54 mg, 0.38 mmol). The reaction mixture was heated at 40° C. for 4 h, cooled to room temperature, diluted with MTBE, and quenched with water. The organic layer was separated and the aqueous layer was extracted with MTBE (3×). The combined organic layer was dried over Na2SO4 and concentrated in vacuo to provide crude product. The crude material was purified by flash chromatography (gradient from 10 to 50% EtOAc/hexanes) to provide the title compound (67 mg, 32%). 1H NMR (CDCl3, 1:1 mixture of amide rotamers) δ 8.19-8.15 (m, 1H), 8.04 (dd, J=11.2, 1.6 Hz, 1H), 7.62 (s, 0.5H), 7.55 (s, 0.5H), 7.50-7.46 (m, 1H), 7.25-7.14 (m, 3.5H), 6.94 (d, J=7.2 Hz, 0.5H), 4.84-4.59 (m, 2H), 4.29-4.13 (m, 2H), 3.96 (s, 3H), 3.82-3.70 (m, 2H), 3.50-3.35 (m, 4H), 3.31-2.88 (m, 4H), 1.89-1.87 (m, 2H), 1.55-1.49 (m, 2H), 1.40-1.05 (m, 6H), 0.93-0.88 (m, 3H), 0.74 (t, J=7.2 Hz, 1.5H), 0.65 (t, J=7.2 Hz, 1.5H); MS(ESI+) m/z 575.6 (M+H)+.
