Participants

Reaction Steps

To a stirred solution containing 34.5 g (0.20 mole) of 4-chloro-3-nitroaniline and 24 g (0.30 mole) of isopropyl mercaptan in 200 ml of DMSO was added dropwise at ambient temperature a solution of 8.0 g (0.20 mole) of sodium hydroxide in 10 ml of water. The addition was exothermic to 60° and the mixture became deep red in color. After three days, the reaction mixture was poured into water and extracted with methylene chloride. The combined extracts were washed with water, dried with anhydrous MgSO4, filtered and concentrated to give 41.1 g (97%) of product as a red-brown syrup.
