Reaction Steps
218 g of chlorosulphonic acid were introduced into a 500 ml round-bottomed flask and 65 g of finely ground 4-methoxy-2-methyl-2,3-dihydrobenzofuran-7-carboxylic acid were added in small amounts. The temperature rose to 38° C. The contents were then heated to 50° C. After cooling, the solution obtained was poured, in small amounts, onto ice, with stirring.
