Abstract
New derivatives of 5,6-dihydrobenzo[5,6]cyclohepta[1,2-b]pyrazolo[4,3-e]pyridin-11(1H)-ones and imines, respectively, have the general formula ##STR1## They and the salts thereof are useful as psychotropic and antiinflammatory agents. PAC SUMMARY OF THE INVENTION This invention relates to new derivatives of 5,6-dihydrobenzo[5,6]cyclohepta[1,2-b]pyrazolo[4,3-e]-pyridin-11(1H)-ones and imines and salts thereof. These new compounds have the general formula ##STR2## R.sup.1 is lower alkyl, phenyl or phenyl-lower alkyl; R.sup.2 is hydrogen, lower alkyl or phenyl; PA1 R.sup.3 is hydroxy, lower alkoxy, halogen or an amine group. The amine group is either an acyclic group ##STR3## wherein R.sup.5 and R.sup.6 each is hydrogen, lower alkyl or phenyl or R.sup.5 and R.sup.6 taken together with the nitrogen form a monocyclic nitrogen heterocyclic of 5 or 6 members in which an additional nitrogen, oxygen or sulfur may be present. PA1 R.sup.4 is oxygen (.dbd.O) or substituted imine (.dbd.NR) PA1 R is lower alkyl or phenyl. PAC DETAILED DESCRIPTION OF THE INVENTION This invention relates to new compounds which are substituted 5,6-dihydrobenzo[5,6]cyclohepta[1,2-b]-pyrazolo[4,3-e]pyridines and are …
