Participants

Reaction Steps

While ice-cooling a suspension of 84 g of stannous chloride-2H2O in 320 ml of glacial acetic acid with stirring until a transparent solution was obtained, hydrochloric acid gas was introduced into the solution and then 14.3 g of 3-chlorosulfonyl-4-methoxyphenylacetone was added to the solution at 25°-30° C. After further stirring the mixture at room temperature for 30 minutes, the reaction mixture obtained was poured into 320 ml of concentrated hydrochloric acid and after diluting the mixture with 640 ml of water, the product was extracted with 400 ml of chloroform. The chloroform layer formed was washed with water and then chloroform was distilled off to provide 10 g of oily 3-mercapto-4-methoxyphenylacetone.
