反応手順

4 ml of acetic acid was added to 5 g (0.02 mol) of 4,4,5,8-tetramethylthiochroman-6-carboxylic acid, further, 6.9 g (0.06 mol) of a 30% hydrogen peroxide aqueous solution was added, and the mixture was heated at 80° C. for 2 hours. 50 ml of a 2% sodium hydrogensulfite aqueous solution was added to the reaction mixture, and a precipitated solid was recovered by filtration to give 5.1 g (yield 90%) of 4,4,5,8-tetramethylthiochroman-6-carboxylic acid-1,1-dioxide.
