실험 절차

To 2 mL of a methanol solution containing 84 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(7-methoxy-2-oxo-5-propionylquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 40 mg of hydroxylammonium chloride was added, and stirred at room temperature for 9.5 hours. To the reaction mixture, aqueous saturated sodium hydrogen carbonate solution was added. The organic layer was separated, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [Silica Gel; Kanto Chemical Co., Inc., Silica Gel 60N, eluent; chloroform:methanol=20:1], to give 84 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(5-(1-(hydroxyimino)propyl)-7-methoxy-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate as a colorless oil.
