실험 절차

To a solution of [4-(benzyloxy)-8-methoxy-3-methylquinolin-2-yl]methanol (250 mg) in THF (10 mL) were added 3-(tetrahydro-2H-pyran-4-ylmethoxy)phenol (185 mg) and 1,1-(azodicarbonyl)dipiperidine (245 mg), followed by dropwise addition of tributylphosphine (0.24 mL) at room temperature and stirring. After 1 hour, tributyl phosphine (0.24 mL) was added thereto, followed by stirring for 12 hours. Ethyl acetate was added to the reaction mixture, and then insolubles were removed by filtration. The filtrate was concentrated under reduced pressure, and then the residue was purified by silica gel column chromatography twice (eluent for the first round: hexane/ethyl acetate=80/20˜67/33˜60/40, eluent for the second round: chloroform˜chloroform/methanol=95/5), and also by thin layer silica gel chromatography (developer: chloroform/methanol=95/5) to obtain 4-(benzyloxy)-8-methoxy-3-methyl-2-{[3-(tetrahydro-2H-pyran-4-ylmethoxy)phenoxy]methyl}quinoline (340 mg).
