Abstract
Dye intermediates of the general formula <FORM:0675226/IV (b)/1> wherein R1 is an alkyl, aralkyl, or aryl group, R2 is an alkyl or aralkyl group, D is the residue of a 5- or 6-membered heterocyclic nucleus, and n is 0 or 1, are prepared by reacting a compound of the general formula <FORM:0675226/IV (b)/2> at a temperature not exceeding 160 DEG C., preferably from 100 DEG to 130 DEG C., with an alkyl or aralkyl p-toluenesulphonate R2O2SC7H7. Dy intermediates wherein the acid radical has other values are prepared by reacting the p-toluenesulphonates with the appropriate inorganic salt. 2 - b - Methyl:b - methoxyvinylbenzthiazole metho-p-toluenesulphonate is prepared by heating together on a water bath 2-acetylmethylene-3-methylbenzthiazoline and methyl p-toluenesulphonate, and the corresponding methiodide is prepared by pouring a hot ethanol solution of the p-toluenesulphonate into aqueous potassium iodide solution. The corresponding etho-p-toluenesulphonate, 2-b -methyl:b -ethoxyvinylbenzthiazole metho- and etho-p-toluenesulphonates, 2 - b - methyl:b - n - propoxyvinylbenzthiazole metho - and etho - p - toluenesulphonates, 2 - b - methyl:b - methoxyvinyl - 1 : 3 : 3 - trimethylindolenium metho-p-toluenesulphonate, and 2-b -methyl : b - phenylethoxyvinylbenzthiazole etho-p-toluenesulphonate are similarly prepared. Specifications 633,824 and 675,227, [Group IV (c)], are referred to.
