Versuchsvorschrift

The 7-[3-(tert-butyldimethylsilyloxy)propylamino]-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (435 mg, 0.913 mmol) obtained in step A was dissolved in THF (9 ml). Thereafter, a 1 M tetrabutylammonium fluoride THF solution (1.1 ml, 1.1 mmol) was added to the obtained solution at a room temperature. The obtained mixture was stirred for 5 hours. Thereafter, methylene chloride was added to the reaction solution. An organic layer thereof was washed with a saturated saline solution, and was then dried over magnesium sulfate, followed by concentration under reduced pressure. The obtained residue was purified by silica gel chromatography (methylene chloride:methanol=30:1), so as to obtain 7-(3-hydroxypropylamino)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (337 mg, 95%).
