Abstract
Abstract A method for the synthesis of N-arylamides of 3-hydroxy-2-naphthoic acid, derived from 5-aminobenzimidazol-2-one and 6-aminobenzoxazol-2-one is presented. These compounds were synthesized by acylation of the corresponding amines with 3-hydroxy-2-naphthoyl chloride in glacial acetic acid, N,N,-dimethylformamide or N-methylpyrrolidone in the presence of anhydrous sodium acetate.
