METHOD FOR PRODUCING 2-CHLORO-5-CHLOROMETHYL-1,3-THIAZOLE

摘要

The invention relates to a method for producing 2-chloro-5-chloromethyl-1,3-thiazole. According to said method, allyl isothiocyanate of formula CH2=CH-CH2-NCS is reacted with 1 to 2 mol of a chlorinating agent per mol allyl isothiocyanate at - 40 DEG C to + 30 DEG C in a solvent that is inert in the reaction conditions. 1 to 5 mol oxidizing agent per mol allyl isothiocyanate is added to the resulting reaction mixture at a reaction temperature of 0 DEG C to the boiling temperature of the solvent used and 2-chloro-5-chloromethyl-1,3-thiazole is isolated from the reaction mixture and optionally, converted into highly pure 2-chloro-5-chloromethyl-1,3-thiazole by crystallization.
