Reaction Steps

1-(Piperidin-4-yl)-7-{[2-(trimethylsilyl)ethoxy]methyl}-3,4-dihydro-1H-pyrrolo[3′,2′:5,6]pyrido[4,3-d]pyrimidin-2(7H)-one (18.5 mg, 0.0460 mmol) in dichloromethane was mixed with phenylmethanesulfonyl chloride (17.5 mg, 0.092 mmol) and triethylamine (12.8 μL, 0.0920 mmol) for 1 hour under cooling with ice. After addition of water, the reaction mixture was extracted with chloroform, and the organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform/methanol=9/1 (v/v)) to give the title compound as a pale yellow solid (18.4 mg, yield 72%).
