HCID 109773182-(Dimethylaminomethyl)-4-(2-aminoethylthiomethyl)thiazole

Procedure

When 2-dimethylaminomethyl-4-hydroxymethylthiazole [prepared in Step D] is reacted with thionyl chloride and the resultant 2-dimethylaminomethyl-4-chloromethylthiazole is reacted with an equimolar amount of cysteamine hydrochloride and two equivalents of base according to the general procedure of Example 33, Step D, the title compound is thereby produced.
