Procedure

232 g (2 mols) of 3,3-dimethyl-4-hydroxy-2-butanone (for the preparation, see Beilstein H 1, E III, 3239, IV 4030 and Bull. Soc. Chim. France 1954, 2849) in 700 ml of absolute pyridine were reacted with 229 g (2 mols) of methanesulphonyl chloride at 0° to 5° C. After leaving the mixture to stand at 20° C. for 12 hours, it was diluted with methylene chloride and extracted by shaking with ice-water. The organic phase was dried and freed from the solvent in vacuo and the residue was fractionated over a column. 332 g (86% of theory) of 2,2-dimethyl-3-oxo-butyl methanesulphonate of boiling point 106°-120° C./0.12 mm Hg were obtained. ##STR79##
