Reaction Steps

16 g of 2,5-dimethoxybenzene-sulphonyl chloride are dissolved in 100 ml of THF, while stirring, and a mixture of 20 ml of concentrated H2SO4 and 60 ml of water is then added, followed by 25 g of zinc dust, added in portions at 50°-55° and stirring is continued overnight at 20°. The THF is then stripped off and the mixture is worked up with water and methylene chloride to give 2,5-dimethoxythiophenol, b.p. 106°-108°/0.3 mm.
