実験手順
Methanesulfonyl chloride (0.023 ml, 0.299 mmol) and triethylamine (0.03 ml, 0.299 mmol) were added at −20° C. to a dichloromethane solution (2 ml) that contained the 7-(3-hydroxymethyl-2-oxopyrrolidin-1-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (80 mg, 199 mmol) obtained in Example 1-46. The obtained mixture was stirred at −20° C. for 2 hours. Thereafter, a saturated ammonium chloride aqueous solution was added to the reaction solution, and the obtained 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->20:1), so as to obtain methanesulfonic acid 2-oxo-1-[1-oxo-3-(2-trifluoromethylphenyl)-1,2-dihydroisoquinolin-7-yl]-pyrrolidin-3-ylmethyl ester (38 mg, 40%) in the form of a colorless oil substance.
