The optimum conditions were reaction temperature 120°C, reaction time 20h, mole ratio of 5-chloromethyl-2-oxazolidinone and sodium phenolate 1:1. 3,5-Dimethylphenol and epichlorohydrin in sodium hydroxide were condensated to give l,2-epoxy-3-phenoxy propane, then the reation of l,2-epoxy-3-phenoxypropane and the carbamate afforded oxazolidinone in the yields of 69.0%~76.0%. The side reaction had been avoided effectively by the uses of the excessive epichlorohydrin and mixed catalysts.
