Reaction Steps

0.88 Gram (2.90 mmol) of 4,4,5-trimethyl-8-chlorothiochroman-6-carboxylic acid-1,1-dioxide was dissolved in-ethanol having a water content of 60%, 0.55 g (8.70 mmol) of a zinc powder was added, and the mixture was refluxed under heat for 5 hours. After the completion of the reaction, 5 ml of water was added, the zinc powder was removed by filtration, and the remainder was extracted with ethyl acetate. The extract was washed with a saturated sodium chloride aqueous solution and dried over anhydrous sodium sulfate. The ethyl acetate was distilled off under reduced pressure to give 0.60 g (yield 78%) of 4,4,5-trimethylthiochroman-6-carboxylic acid-1,1-dioxide.
