Reaction Steps
A mixture of 2-[4-(benzyloxycarbonyl)piperazin-1-yl]-4-[trans-(2-buten-1-yl)oxy]quinazoline (1.30 g), a solution of osmium tetroxide in t-butanol (osmium tetroxide 106 mg/t-butanol 8.36 g) (312 mg) and 4-methylmorpholine N-oxide (382 mg) in water (2 ml)--acetone (15 ml) is stirred at room temperature for 14 hours. Acetone is distilled off from the reaction mixture under reduced pressure, and the resultant product is diluted with ethyl acetate, and the mixture is washed with 10% aqueous sodium sulfite solution and water. The ethyl acetate solution is dried over anhydrous magnesium sulfate and evaporated to dryness under reduced pressure, and the residue is purified by medium pressure liquid column chromatography (eluent, chloroform:methanol=100:1, v/v) to give 2-[4-(benzyloxycarbonyl)piperazin-1-yl]-4-[(2RS,3RS)-(2,3-dihydroxybutan-1-yl)oxy]quinazoline (1.02 g) as foam.
