Compounds having the formula:
wherein R4 is hydrogen or chloro;
R5 is carboxy, an ester thereof, or tetrazolyl;
R2 is hydrogen, halo, or alkoxy of 1 to 4 carbon atoms; and
R3 is hydrogen or bromo, with the proviso that when R4 is hydrogen, R5 is carboxy and R2 or R3 is other than hydrogen; and that when R4, R2 and R3 are all hydrogen, R5 is tetrazolyl; the stereoisomers thereof and the pharmaceutically acceptable salts thereof. The compounds of formula B wherein R5 is carboxy or tetrazolyl have pharmaceutical utility eg. as anti-inflammatory agents. The compounds where R5 is a carboxylic ester are intermediates for the corresponding acids. Pharmaceutical composition containing the active compounds are also disclosed.
