Reaction Steps

930 ml of chlorosulphonic acid were introduced into a 1-liter round-bottomed flask and 165 g of chroman-8-carboxylic acid were then added in small amounts, while maintaining the temperature between 0° C. and 10° C. by cooling. The solution was stirred for 1 hour at 10° C., and then allowed to stand overnight at ambient temperature. It was then poured in small amounts onto ice, while stirring and maintaining the temperature at 0° C. by cooling externally and by introducing ice into the flask.
