Acetic Acid → HCID 23156793, compound

Participants

Reaction Steps

0.05 ml of acetic acid and 13.2 mg (0.168 mmol) of sodium cyanoborohydride were added to 0.5 ml of a methanol solution containing 14.7 mg (0.0241 mmol) of the 7-(2-morpholin-4-ylethylamino)-3-phenyl-2H-isoquinolin-1-one obtained in Example 15. The obtained mixture was stirred at a room temperature for 6 hours. Thereafter, a saturated sodium bicarbonate aqueous solution was added to the reaction solution, and the mixture was then extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and was then concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (methylene chloride:methanol=20:1), so as to obtain 12.8 mg (84%) of 7-[methyl(2-morpholin-4-ylethyl)amino]-3-phenyl-2H-isoquinolin-1-one in the form of a yellow solid.
