Procedure
Chlorocarbonyl sulphenyl chloride (41.9 g, 0.32 mol) is added dropwise to a stirred solution of isobutyramide (25.2 g, 0.29 mol) under dry nitrogen at room temperature. When the addition is complete, the mixture is refluxed for 8 hours, during which time hydrogen chloride gas is evolved. The solvent is removed in vacuo and the residue is distilled to give 5-isopropyl-[1,3,4]oxathiazolin-2-one (37 g, 88%) as a yellow oil, b.p. 58°-59° C./8 mmHg.
