Bis(2-chlorothiazolyl-5-methyl)amine and its salts, and process for working up reaction mixtures comprising 5-aminomethyl-2-chlorothiazole and bis(2-chlorothiazolyl-5-methyl)amine
摘要:
As a result of a special precipitation, it is possible to work up reaction mixtures containing 5-aminomethyl-2-chlorothiazole and bis(2-chlorothiazolyl-5-methyl)amine in an advantageous manner and to isolate bis(2-chlorothiazolyl-5-methyl)amine or its salts.
