factors of carboxylic acids, their acidity, and the tertiaryamines were observed in the reaction. Phosphorous acid provided a better result than the monoesters. In addition, the chain length of carboxylic acids in the case of the esters influenced the yields of the anilides, which decreased with an increase in the chain length. The structural effect of tertiaryamines was studied on pyridine derivatives
