Indan derivatives, namely, 5-(5', 6'-dichloroindan-1'-yl)-tetrazole (12a) and 5-(5', 6'- dichloroindan-1'-yl)-methyltetrazole (12b), were synthesized conveniently from 5, 6- dichloroindan-1-carboxylic acid (9a) and 5, 6-dichloroindan-1-acetic acid (9b), respectively, as potential analgesic and anti-inflammatory agents. The analgesic and anti-inflammatory properties of 9a, 9b, 12a and 12b were evaluated by the acetic acid induced writhing in ...
