Triethylamine → 6-Methoxy-1-[1-(1-methyl-1H-imidazole-4-sulfonyl)-piperidin-4-yl]-3,4-dihydro-isoquinoline

참여 물질

반응 단계

To a stirred solution of 6-methoxy-1-piperidin-4-yl-3,4-dihydro-isoquinoline (0.094 g, 0.385 mmol) and triethylamine (0.078 g, 0.77 mmol) in CH2Cl2 (3 ml) was added 1-methyl-1H-imidazole-4-sulfonyl chloride (0.070 g, 0.385 mmol). The reaction mixture was stirred at RT under an atmosphere of N2 overnight. The reaction mixture was diluted with CH2Cl2 (10 ml) and washed with water (2×5 ml). The organic layer was dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified via radial chromatography (SiO2, 1 mm, CH2Cl2 to 5% MeOH/CH2Cl2) to give the product as an oil (0.084 g, 0.216 mmol, 56% yield).
