Abstract
Various 1,5,6,11-tetrahydrobenzo[5,6]cyclohepta[1,2-b]-pyrazolo[4,3-e]pyridine derivatives and their salts of the formulas ##STR1## wherein R.sub.1 is lower alkyl, phenyl, or phenyl-lower alkyl; R.sub.2 is hydrogen, lower alkyl or phenyl; R.sub.3 is hydrogen, halogen, or lower alkoxy; R.sub.4 is hydrogen, ##STR2## ALKYL; R.sub.5 is hydrogen or lower alkoxy; R.sub.6 is hydrogen, ##STR3## n is an integer from 2 to 6; R.sub.7 and R.sub.8 are the same or different and each is lower alkyl or R.sub.7 and R.sub.8 taken together with the N-atom form a heterocyclic ring of the formula ##STR4## wherein R.sub.9 is hydrogen or lower alkyl; R.sub.10 and R.sub.11 are the same or different and each is hydrogen or lower alkyl or R.sub.10 and R.sub.11 taken together with the N-atom form a heterocyclic ring of the formula ##STR5## wherein R.sub.9 is as defined above; are disclosed. These compounds possess useful antiinflammatory activity as well as psychotropic activity. PAC SUMMARY OF THE INVENTION This invention relates to new 1,5,6,11-tetrahydrobenzo[5,6]cyclohepta[1,2-b]pyrazolo[4,3-e]pyridine derivatives and their salts of the formulas ##STR6## R.sub.1 is hydrogen, lower alkyl, phenyl, or pheny…
