A solution of 136.1 parts of S-5-(3-methylbutoxy)-2-propylphenyl N,N-dimethylthiocarbamate and 280 parts of potassium hydroxide in 1000 parts of digol was stirred under nitrogen at 120° - 130° for 9 hours, after which no dimethylamine could be detected in the effluent nitrogen. The mixture was cooled, poured into 8000 parts of water and the resulting solution was acidified to pH 1 with hydrochloric acid. The mixture was extracted with ether and the latter was washed with water, dried over magnesium sulphate, filtered and evaporated to dryness to give 95.7 g of the desired product 5-(3-methylbutoxy)-2-propylthiophenol.
