By using diazomethane for the methylation of 5, 5-dimethyl-2, 4-dioxo-oxazolidine as a method of manufacturing 3, 5, 5-trimethyl-2, 4-dioxo-oxazolidine, a good yield was obtained. Methylation in good yield was obtained from 5, 5-dimethyl-2, 4-dioxo-thiazolidine, 2, 4-dioxo-thiazolidine and 2, 4-dioxo-oxazolidine as heterocyclic compounds of -CO-NH-CO-type.
