N-sulfamyl-propionamidine derivatives are prepared by the reaction of 3-substituted-propionitriles with an oxonium hydrochloride, preferably of 1,4-dioxane, in the presence of sulfamide in a close system at pressures between 0.5 kg/cm and 4.0 kg/cm. These compounds are useful in the preparation of famotidine, an anti-ulcer agent.
N-磺胺基丙酰胺衍生物是通过3-取代丙腈与氯化氢氧锆反应制备的,最好使用1,4-二氧六环,在0.5千克/平方厘米至4.0千克/平方厘米的压力下,在封闭系统中存在磺胺基的情况下。这些化合物在制备抗溃疡药法莫替定中很有用。
