Abstract
Phthalic anhydride was treated with secondary amines in acetic acid yielding 2-(diethyl (or) 4-alkylpiperazine or morpholine-1-carbonyl) benzoic acids. The latter were reacted, again, with secondary amines and arylamines by using the coupling reagent HATU and Et3N as a base in DMF giving the novel symmetrical o-phthalic acid diamides , unsymmetrical o-phthalic acid diamides , and primary amidic-secondary amidic containing unsymmetrical o-phthalic acid diamides , respectively.
