HCID 211001851-(5-Ethanesulfonyl-thiazol-2-yl)-piperazine hydrochlorideYield 86%

Procedure

Prepared in analogy to example 4 (d) from 4-(5-ethanesulfonyl-thiazol-2-yl)-piperazine-1-carboxylic acid tert-butyl ester and hydrogen chloride solution. The crude material was purified by recrystallisation from ether to afford the title compound as a light brown crystalline solid (yield 86%). MS (m/e): 262.0 (M+H+, 100%).
