Abstract
Cyanoethyl thiazyl sulphides and amides and esters thereof are prepared by combining 2-mercaptothiazoles with acrylonitrile in presence of an alkali metal or alkaline compound thereof, such as sodium, sodium hydroxide, sodium alcoholates, sodium mercaptides, or potassium hydroxide or a basic tertiary amine as catalyst. 2 - Mercaptobenzothiazole, 2-mercapto - 4 - methylthiazole, 2 - mercapto - 4 - phenyl thiazole, or any 2-mercapto naphthol thiazole or any 2-mercapto benzothiazole, such as 2-mercapto-5-methyl-, 2-mercapto-6-methyl-, 2 - mercapto - 4,6 - dimethyl-, 2 - mercapto - 4 - methyl-, 2 - mercapto - 4 - methyl - 6 - chlor-, 2-mercapto-6-ethoxy-, 2-mercapto-6-nitro-, and 2 - mercapto - 6 - amino - benzothiazole may be used. An example is given of the preparation of b -cyanoethyl benzothiazyl sulphide. The nitriles may be converted to amides by acid hydrolysis, e.g. b -(2-thiobenzothiazyl) propionamide which may be converted to the acid, e.g. carboxyethyl benzothiazyl sulphide, which may be converted to the ethyl or other alkyl, allyl, furyl or aryl ester. The esters may also be prepared by alcoholysis of cyanoethyl benzothiazyl sulphide in presence of gaseous HCl.
