ABSTRACT:
Heterocyclic esters of alkylphenyl benzopyranopyridines represented by the formula ##STR1## wherein R.sub.1 is hydrogen, loweralkyl, loweralkanoyl, cycloalkylloweralkyl, cycloalkylloweralkanoyl, loweralkenyl, loweralkynyl, haloloweralkenyl, phenylloweralkyl, phenylloweralkenyl or phenylloweralkynyl; R.sub.2 is loweralkyl; R.sub.3 is ##STR2## WHEREIN X is a straight or branched chain alkylene group having from one to eight carbon atoms, a is an integer from 1 to 4, b is an integer from 1 to 4 and Z is CH.sub.2, O, S or NR.sub.7, with R.sub.7 being hydrogen or loweralkyl, with the limitation that when X is O, S or NR.sub.7, the sum of a and b is 3 or 4; and R.sub.8 is hydrogen or loweralkyl; Y is a straight or branched chain alkylene group having from one to ten carbon atoms; and each R.sub.4 and R.sub.5 and R.sub.6 are the same or different members of the group consisting of hydrogen, halo, trifluoromethyl or loweralkyl; and the pharmaceutically acceptable acid addition salts thereof.
