Summary 2-Ethylmercapto-4-methyl-6-thiocyanopyrimidine is formed by interaction of potassium thiocyanate with 2-ethylmercapto-4-methyl-6-chloro-pyrimidine in boiling ethyl alcohol solution. 2. This thiocyanate distils at 155-158'at 5 mm. and is rearranged to its isomeric form, the isothiocyanate,(1) by heating with alcohol at 100'and (2) by digestion in boiling xylene.
