carboxylic acid to amide mechanism
How to make amide from amine?
First, considering the nucleophilic addition-elimination mechanism, the reaction of an amine with a carboxylic acid may seem to be a suitable way of making amide: When comparing the – OH and RNH –, the hydroxide ion is a better leaving group. Recall, the p K a (H 2 O) = 15.7, and the p K a (RNH 2) = 38.
