実験手順

The 7-((S)-5-aminomethyl-2-oxooxazolidin-3-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (30 mg, 0.07 mmol) obtained in step B was dissolved in methylene chloride (0.3 ml). Thereafter, pyridine (30 μl, 0.37 mmol) and methanesulfonyl chloride (5.8 μl, 0.07 mmol) were added to the solution, and the obtained mixture was stirred at 0° C. for 30 minutes. Thereafter, water was added to the reaction solution, and the mixture was then extracted with methylene chloride. The extract was washed with water and a saturated saline solution, and was then dried over magnesium sulfate. Thereafter, the solvent was distilled away under reduced pressure. The obtained residue was purified by silica gel column chromatography (methylene chloride:methanol=20:1), so as to obtain N-{(R)-2-oxo-3-[1-oxo-3-(2-trifluoromethylphenyl)-1,2-dihydroisoquinolin-7-yl]oxazolidin-5-ylmethyl}methanesulfonamide (12.6 mg, 36%) in the form of a colorless solid.
