Methyl sulfate(1-) → 3-Butyl-5-methyl-1,3,5-oxadiazinane-2,4,6-trione

Participants

Reaction Steps

The process described in example 14 is carried out without distillation of the solvent. 72 g of methyl sulfate (0.57 mole) are added to the solution of the salt of tributylbenzylammonium 3-butyl-1,3,5-oxadiazine-2,4,6-trione. The solvent is evaporated after 5 hours of reaction at 25° C. The solid residue is washed with water and with carbon tetrachloride. 88 g of 3-butyl-5-methyl-1,3,5-oxadiazine-2,4,6-trione (yield: 81%) of the formula (II) are obtained.
