1-Benzylpiperidine-4-carbaldehyde → HCID 54153280, compound

Participants

Reaction Steps

Under ice cooling, 1.70 g of a 28% sodium methoxide·methanol solution was added to 1.96 g of 4-(1-oxoindan-5-yl)amino-5,6-dihydro-7H-cyclopenta[d]pyrimidine dissolved in tetrahydrofuran, and then 1.80 g of 1-benzyl-4-formylpiperidine was added dropwise thereto. After the mixture was stirred for 1.5 hours, a saturated saline solution was added to the reaction mixture, and the mixture was extracted with chloroform. The extract was dried over anhydrous sodium sulfate and condensed under reduced pressure. The obtained residue was applied to silica gel column chromatography and then recrystallized from chloroform to obtain 1.35 g of the title compound as pale yellow crystal.
