The invention relates to a dealkylation chemical process for preparing imidazoquinoxalines bearing hydrogen substitution in the five position, and to valuable pharm-intermediates of the formula I ##STR1## wherein ##STR2## wherein R' is C.sub.1-6 -alkyl, C.sub.3-7 -cycloalkyl, phenyl, thienyl, or C.sub.1-3 -alkoxymethyl and wherein R.sup.6 and R.sup.7 independently are hydrogen,halogen or CF.sub.3, used in that process. The intermediates also have anticonvulsant and anxiolytic properties.
本发明涉及一种去烷基化化学过程,用于制备在五位带有氢取代的咪唑喹啉化合物,并且涉及公式I的有价值的药物中间体:##STR1## 其中:##STR2## 其中R'是C.sub.1-6烷基,C.sub.3-7环烷基,苯基,噻吩基或C.sub.1-3-烷氧甲基,R.sup.6和R.sup.7独立地为氢,卤素或CF.sub.3,用于该过程。这些中间体还具有抗惊厥和抗焦虑的特性。
