Abstract

Guanidines (I; R, R1 = C1-4 alkyl, Het-(CH2)m-z-(CH2)n-,here, Het is alkyl, hydroxyalkyl, hydroxy, halogen, amino substituted or unsubstituted imidazole, pyridine, thiadiazole, Z = O, S, amino or methylene, m=0,1,2,3 integer, n = 1,2,3 integer), useful antagonist to H2 receptor, were prepd. by treatment of alkylisothiocyanates with metallic cyanamide salts. The resulting carbodiimides were reacted with amine to give I.
