Reaction Steps

The 2-oxo-3-[1-oxo-3-(2-trifluoromethylphenyl)-1,2-dihydroisoquinolin-7-yl]oxazolidin-5-carboxylic acid (12.5 mg, 0.03 mmol) obtained in Example 2-4 and a 25% ammonia aqueous solution (3.06 μl, 0.045 mmol) were dissolved in isopropanol (0.3 ml). Thereafter, 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (13.3 mg, 0.045 mmol) was added to the solution, and the obtained mixture was then stirred at a room temperature for 3.5 hours. Thereafter, water was added to the reaction solution, and the mixture was then extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and the solvent was then distilled away under reduced pressure. The obtained residue was purified by silica gel column chromatography (methylene chloride:methanol=30:1), so as to obtain 2-oxo-3-[1-oxo-3-(2-trifluoromethylphenyl)-1,2-dihydroisoquinolin-7-yl]oxazolidin-5-carboxylic amide (9.8 mg, 78%) in the form of a colorless amorphous substance.
