실험 절차

Triethylamine (128 μl) and methanesulfonyl chloride (71 μl) were added to a solution obtained by dissolving the 7-(5-hydroxymethyl-2-oxooxazolidin-3-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (186.7 mg, 0.462 mmol) obtained in step B in methylene chloride (2.3 ml), under cooling on ice. The obtained mixture was stirred for 30 minutes. Thereafter, a saturated ammonium chloride aqueous solution was added to the reaction solution, followed by extraction with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and was then concentrated. The obtained residue was purified by silica gel column chromatography (ethyl acetate:hexane=2:1, and then methylene chloride:methanol=30:1), so as to obtain 2-oxo-3-[1-oxo-3-(2-trifluoromethylphenyl)-1,2-dihydroisoquinolin-7-yl]oxazolidin-5-ylmethyl methanesulfonate (169.1 mg; yield: 76%) in the form of a colorless foaming substance.
