Reaction Steps

2-(5-methyl-2-phenyloxazol-4-yl)ethanol (1.02 g), 3-hydroxybenzaldehyde (0.73 g) and triphenylphosphine (1.57 g) were dissolved in dichloromethane (10 ml) and thereto was added 1,1′(azodicarbonyl)dipiperidine (1.74 g) at 0° C. and the mixture was stirred at room temperature for 2 hours. To the reaction mixture was added hexane and the solid was filtered off. The filtrate was concentrated. The residue was purified by column chromatography on silica gel (methanol:chloroform=1:100) to give the title compound (1.30 g) having the following physical data.
