There are described compounds of the formula ##STR1## where n is 0 or 1; R.sub.1 is independently hydrogen, loweralkyl, loweralkenyl, loweralkynyl, loweralkoxycarbonylloweralkyl, loweralkylaminocarbonylloweralkyl, aminocarbonylloweralkyl, arylloweralkyl, phenyl, nitrophenyl, cyanophenyl, trifluoromethylphenyl, aminophenyl, loweralkanoylaminophenyl, loweralkoxycarbonyl, arylloweralkoxycarbonyl, aryloxycarbonyl, loweralkylaminocarbonyl, arylloweralkylaminocarbonyl, arylaminocarbonyl, alkanoyl, arylloweralkanoyl, aroyl, alkenoyl, alkynoyl or --R.sub.5 --NR'R" where R.sub.5 is loweralkylene, loweralkenylene or loweralkynylene and R' and R" are each independently loweralkyl or alternatively the group --NR'R" as a whole is 1-pyrrolidinyl, 1-piperidinyl, 4-morpholinyl, 4-loweralkyl-1-piperazinyl or 4-aryl-1-piperazinyl;R.sub.2 is hydrogen or loweralkyl;R.sub.3 and R.sub.4 are each independently hydrogen or loweralkyl, or alternatively R.sub.3 and R.sub.4 taken together form --CH.dbd.CH--CH.dbd.CH-- so that the moiety ##STR2## becomes an indazole ring; and X is hydrogen, nitro, amino, halogen, loweralkanoylamino, arylloweralkanoylamino, aroylamino, alkylamino, arylloweralkylamino, loweralkyl, and cyano; which compounds are useful as analgesic and antidepressant agents.
