Versuchsvorschrift
To a solution of 45 g of 3-chloroprop-1-enyl isothiocyanate in 90 ml of 1,2-dichloroethane, 50.5 g of sulphuryl chloride was added over 10 hours at -10° C. The reaction mixture was allowed to warm to 25° C. overnight, to complete the reaction. The solution was cooled to -15° C. and the product, a pale yellow solid, was isolated by filtration and washed with hexane. 38.2 g of 2-chloro-5-(chloromethyl) thiazole hydrochloride was thus obtained, having a melting point of 59°-61° C. and being a yield of 61.6%.
