Versuchsvorschrift

The reaction of 5-[(2-aminoethyl)thiomethyl]thiazole (2.24 g.) with methyl isothiocyanate (0.94 g.) in ethanol (10 ml.) gave a thiourea which was purified by chromatography on a column of silica gel with ethyl acetate as eluant. Recrystallisation from isopropyl acetate-methyl ethyl ketone-ether gave N-methyl-N'-]2-(5-thiazolylmethylthio)ethyl]thiourea (2.1 g.), m.p. 86°-88°. (Found: C, 38.6; H, 5.4; N, 16.9; S, 38.6. C8H13N3S3 requires: C, 38.8; H, 5.3; N, 17.0; S, 38.9).
