Abstract
Title compds. (I; X = C=O, CHC1, CHBr, CH2 or CHOR4, Y= C1-C4 alky1, C1-C4 alkoxy, H, trifluoromethyl, m=0, 1, 2, 3, Z= COOR5, CH2OR5, CONHR5 or CONHCOR5, R1-R5=H, or C1-C4 alkyl), with antiinflammatory activity and analgesic, were prepd. Thus, the corresponding 2 acids were obtained by saponifying diester, which was prepd. by reacting &-bromotoluylic acid ester (n, Y group is substituted) and hydroxypheny1 acetic acid ester (&-position is substituted to R1 or R2), dehydrating and cyclizing to give I.
