Participants

Reaction Steps

To a solution of 4-(6,8-dimethoxyisoquinolin-3-yl)-2,6-dimethylphenol (0.309 g, 1.0 mol) in anhydrous THF (20 mL), triphenyl phosphene (0.52 g, 2.0 mmol), 4-(2-hydroxyethyl)morpholine (0.262 g, 2.0 mmol) and N,N-diisopropylethylamine (0.387 g, 3.0 mmol) were added. To this stirred solution was added diethylazodicarboxylate (0.348 g, 2.0 mmol). The reaction mixture was stirred at room temperature overnight under nitrogen, then diluted with ethyl acetate (100 mL). The organic layer was washed with water and brine, and dried over anhydrous Na2SO4. The solvent was removed under reduced pressure. The crude material was purified by column chromatography to give 3-[3,5-dimethyl-4-(2-morpholin-4-ylethoxy)phenyl]-6,8-dimethoxyisoquinoline (0.54 g) as a white solid.
