Abstract
Alkylphenyl benzopyranopyridines represented by the formula ##STR1## where R 1 is hydrogen, loweralkyl, loweralkanoyl, cycloalkylloweralkyl, cycloalkylloweralkanoyl, loweralkenyl, loweralkynyl, haloloweralkenyl, phenylloweralkyl, phenylloweralkenyl or phenylloweralkynyl; R 2 is loweralkyl; R 3 is hydrogen; Y is a straight or branched chain alkylene group having from one to ten carbon atoms; and each R 4 and R 5 and R 6 are the same or different members of the group consisting of hydrogen, halo, trifluoromethyl or loweralkyl; and the pharmaceutically acceptable salts thereof.
Claims
exact text as granted — not AI-modifiedI claim:
