Reaction Steps

A mixture of chlorzoxazone, 3-(t-butoxycarbonylamino)-1-propene, palladium diacetate, tritolylphosphine, and acetonitrile is cooled to −78° C., degassed, and sealed in a reaction tube. The mixture is kept at 50° C. with stirring for 60 hours, then cooled and opened and the acetonitrile removed under vacuum. The residue is dissolved in ethyl acetate and washed successively with 5% aqueous NaHCO3 and brine. After drying over Mg2SO4, the mixture is filtered and evaporated. Silica gel chromatography gives 5-(3-(t-butoxycarbonylamino)-1-propenyl)-2-benzoxazolone.
