8-azabicyclo¬3.2.1 octane derivatives and their use as anticholinergics

摘要

Diphenylalkanoic acid azabicyclooctane ester quaternary salts are new. They can be prepared via new diphenylalkanoic acid azabicyclooctane esters. diphenylalkanoic acid azabicyclooctane ester quaternary salts of compounds of formula (I) are new: X- = anion; A = group (a), (b) or (c): R1,R2 = 1-4C alkyl optionally substituted with OH or halo; R3-R6 = H; 1-4C alkyl; 1-4C alkoxy; OH; CF3; CN; NO2; or halo; and R7 = H; halo; 1-4C alkyl optionally substituted with halo, OH or 1-4C alkoxy; 1-4C alkoxy; 1-4C haloalkoxy; 1-4C alkyl-CO-O-; 1-4C haloalkyl-CO-O-; or CF3-CO-O-. Independent claims are also included for: (1) preparation of compounds (I); and (2) diphenylalkanoic acid azabicyclooctane ester intermediates of formula (IV);
