    Abstract: The invention relates to processes for preparing 2-aminomethyl-4-cyanothiazole and its salts of the formulae Ia and Ibin whichn=1 or 2 andfor n=1, X is chloride, bromide, triflate and hydrogen sulfate andfor n=2, X is sulfate, which comprises the process step where the aminonitrile of the formula IIis stirred with a cysteine ester of the formula III,in which R is branched or linear C1-10-alkyl orwhere n=0, 1 or 2 and R is branched or linear C1-C10C10-alkyl or C1-C4-alkoxy or C1-C4-dialkylamino in an inert solvent in the presence of a base at from 0° C. to 80° C. until the reaction has essentially proceeded to completion, and to the compounds of the formulae Ia and Ib.
