Participants

Reaction Steps

1-Benzyl-1′H-spiro[piperidine-4,2′-quinazolin]-4′ (3′H)-one (5.0 g) and 10% palladium-carbon (500 mg) were suspended in methanol (200 mL), and the suspension was stirred at room temperature for 2 days under a hydrogen atmosphere. The catalyst was removed by filtration through celite. The solvent was evaporated under reduced pressure and the residue was crystallized from ethanol/ether to give the object product (2.34 g, 41%).
