Procedure

A mixture of 2-[2,2,2-trifluoroethyl]guanidino-4-chloromethylthiazole hydrochloride (4.6 g.) in EtoH (75 ml.) and methyl 3-mercaptopropionate (2.47 ml.) at 5° was treated dropwise with aqueous sodium hydroxide (1.8 g. in 15 ml. of water) over 10 minutes. The resulting solution was allowed to reach room temperature and was stirred for 1 hour. It was then poured into water and the precipitate filtered and crystallised from EtOH to give methyl 3-[2-(2-[2,2,2-trifluoroethyl]guanidino)thiazol-4-ylmethylthio]propionate (1.93 g), m.p. 96°-98°.
