PROCEDURE

实验过程

A mixture of 2,2,2-trifluoroethyl isothiocyanate (0.68 g.) and 2-amino-4-[2-(2-cyano-3-methylguanidino)ethylthiomethyl]thiazole (1.08 g.) in dimethylformamide (5 ml.) was maintained at 60° for 4 hours and then evaporated to dryness. The residue was recrystallised from acetonitrile to give 2-[3-(2,2,2-trifluoroethyl)thioureido]-4-[2-(2-cyano-3-methylguanidino)ethylthiomethyl]thiazole, m.p. 157°-158°.
