Versuchsvorschrift

The 2-oxo-3-[1-oxo-3-(2-trifluoromethylphenyl)-1,2-dihydroisoquinolin-7-yl]oxazolidin-5-ylmethyl methanesulfonate (169.1 mg, 0.351 mmol) obtained in step C was dissolved in N,N-dimethylformamide (1.3 ml). Thereafter, sodium azide (96.2 mg, 1.33 mmol) was added to the obtained solution, and the mixture was then stirred at 65° C. for 4 hours. Thereafter, water was added to the reaction solution, followed by extraction with ethyl acetate. The extract was washed with a saturated saline solution, and was then dried over anhydrous sodium sulfate, followed by concentration under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate:hexane=2:1 to 3:1), so as to obtain 7-(5-azidomethyl-2-oxooxazolidin-3-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (139.6 mg; yield: 93%) in the form of a colorless solid.
