Versuchsvorschrift

Methylamine (40% methanol solution) was added to the 7-(3-bromopropylamino)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (245 mg, 0.576 mmol) obtained in step A, and the obtained mixture was then stirred at a room temperature for 3 hours. Thereafter, the reaction solvent was distilled away, and the obtained residue was purified by amino silica gel column chromatography (methylene chloride:methanol=20:1), so as to obtain 142 mg of 7-(3-methylaminopropylamino)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (66%).
