실험 절차

To a solution methyl 4-(4-(dibutylcarbamoyl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-2-yl)-3-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzoate (180 mg, 0.28 mmol) in DCM (4 mL) was added trifluoroacetic acid (4 mL) at 0° C. The reaction mixture was allowed to warm to room temperature and stirring was continued for 4 h. The reaction mixture was concentrated in vacuo. The resulting residue was dissolved in DCM and washed with sat. NaHCO3 solution. The organic layer was dried over Na2SO4 and concentrated to give crude product. The crude material was purified by flash chromatography (gradient from 0 to 5% methanol/CHCl3) to provide the title compound (130 mg, 91%). 1H NMR (CD3OD) δ 8.25-8.06 (m, 2H), 8.00-7.50 (m, 2H), 7.28-6.83 (m, 4H), 4.36 (br s, 1H), 4.01 (br s, 4H), 3.60-3.24 (m, 6H), 2.88-2.69 (m, 2H), 1.60-1.52 (m, 4H), 1.36-1.30 (m, 4H), 1.05-0.90 (m, 6H); MS(ESI−) m/z 515.2 (M−H)−.
