Reaction Steps
126 Parts of o-mercaptophenol are added in portions, in a nitrogen atomsphere and whilst cooling, to a stirred mixture of 138 parts of potassium carbonate, 166 parts of potassium iodide and 500 parts by volume of acetone. The mixture is thereafter heated to boiling point and 268 parts of 1-methoxy-2-propyl-p-toluenesulphonate are added drop by drop. The mixture is boiled under reflux for 24 hours, filtered and evaporated. The residue is taken up in 750 parts by volume of toluene, and washed once with water, and then twice each time with 250 parts by volume of 15% strength sodium hydroxide solution. The alkaline extract is immediately neutralised with hydrochloric acid and extracted with toluene. The toluene solution is dried over anhydrous sodium sulphate, filtered and evaporated. The residue is distilled in a high vacuum.
