Thioformamide derivatives of formula: ##STR1## in which R is hydrogen or alkyl (1 to 4 C), R.sub.1 is alkyl (1 to 4 C), and X denotes sulphur or oxygen and Y is sulphur, oxygen, methylene radical, or, when X is oxygen, a valency bond, are inhibitors of gastric secretion and therefore useful in the treatment of gastric ulcers. They may be made by reaction of an amine R--NH.sub.2 with a corresponding thioester or, when R is alkyl, by reaction of an alkyl isothiocyanate with the product of reacting a base with a compound of formula: ##STR2##
Thioformamide衍生物的化学式如下:##STR1## 其中R是氢或烷基(1到4碳),R.sub.1是烷基(1到4碳),X表示硫或氧,Y是硫、氧、亚甲基或当X为氧时是一个价键,这些化合物是胃分泌抑制剂,因此在胃溃疡治疗中非常有用。它们可以通过氨基R--NH.sub.2与相应硫酯或当R为烷基时,通过烷基异硫氰酸酯与化合物##STR2## 通过碱与化合物发生反应制备而成。
