Abstract:Six N-benzyl amides were synthesized by amidation reaction of 3-methoxy benzylamine, (S)-α-phenylethylamine, (R)-α-phenylethylamine or benzylamine with pentanoic acid, hexadecanoic acid, palmitic acid, 4-nitrobenzoic acid or m-chlorobenzoic acid, respectively, using p-toluenesulfonic acid as the catalyst in toluene. The yields were 10.7%~22.3%, and N-(3-methoxybenzyl) pentanamide was a new compound. The structures were characterized by 1H NMR, IR and elemental analysis.
