: The mixture is heated under reflux to favor product formation. : The mixture is heated under reflux to

: The molecule diffuses into nerve cells and binds to voltage-gated sodium channels .

Chemically known as the ethyl ester of , benzocaine is typically synthesized through Fischer esterification . In a laboratory setting, this involves reacting 4-aminobenzoic acid with absolute ethanol in the presence of a strong acid catalyst, such as concentrated sulfuric acid.
