m-Chloroperbenzoic acid → HCID 19871317, compound

Participants

Reaction Steps

A solution of 757 mg of 3-dimethylcarbamoyloxy-5-methylthiomethylisoxazole in 5 ml of methylene chloride was added dropwise over a period of 30 minutes, with stirring, to an ice-cooled solution of 711 mg of m-chloroperbenzoic acid in 15 ml of methylene chloride. The mixture was then stirred for a further 30 minutes, after which it was filtered and the precipitate was washed with 2 ml of methylene chloride. The filtrate and the washings were combined, and then the solvent was removed by distillation, leaving a colourless, crystalline residue, which was recrystallized from diethyl ether, to give 700 mg (yield 86.1%) of 3-dimethylcarbamoyloxy-5-methylsulphinylmethylisoxazole, in the form of colourless needles melting at 84°-85° C.
