Reaction Steps

To a solution of 2-[4-(benzyloxycarbonyl)piperazin-1-yl]-4-[(3S)-(3,4-dihydroxybutan-1-yl)oxy]quinazoline (2.00 g) in methanol (40 ml) is added 10% palladium/carbon (300 mg), and the mixture is stirred under hydrogen atmosphere and under atmospheric pressure at room temperature for 21.5 hours. The reaction mixture is filtered, and the filtrate is evaporated to dryness under reduced pressure, and the residue is washed with acetone to give 4-[(3S)-(3,4-dihydroxybutan-1-yl)oxy]-2-(1-piperazinyl)quinazoline (1.10 g) as crystals.
