Hydrogen Peroxide → HCID 23450713, compound

Participants

Reaction Steps

A 30-ml eggplant type flask was charged with 0.75 g (3.2 mmol) of the 4,5,8-trimethylthiochroman-6-carboxylic acid, 1.1 g (9.5 mmol) of 30% hydrogen peroxide and 1 ml of acetic acid, and the mixture was allowed to react at 100° C. for 2 hours. The reaction mixture was poured into a sodium hydrogensulfite aqueous solution and extracted with ethyl acetate. The extract was washed with a saturated sodium chloride aqueous solution and dried over sodium sulfate, and the solvent was distilled off to give 0.76 g (yield 98%) of 4,5,8-trimethylthiochroman-6-carboxylic acid-1,1,dioxide.
