摘要：

5-Amino-N-(2,2-dialkoxyethyl)pyrazole-4-carboxamides obtained by hydrolytic cleavage of 5-(2,2-diethoxyethyl)pyrazolo[3,4-d]pyrimidin-4-ones or by condensation of 3-(dimethylamino)-N-(2,2-dimethoxyethyl)-2-cyanoacrylamides with alkylhydrazines in formic acid react with benzylthiol or thiophenols to afford 7-benzyl(aryl)sulfanyl-5,6,7,8-tetrahydro-1H-pyrazolo[3,4-e][1,4]diazepin-4-ones.
