Synthesis of benzocaine reaction

WebAug 6, 2013 · Synthesis of Benzocaine Purpose: To prepare benzocaine (a local anesthetic) from p-aminobenzoic acid and ethanol, via a Fischer esterification reaction. Note: The ethanol used was denatured, and contained about 90% ethanol by weight. Experimental: 1)10.02 g PABA (0.7306 moles) were placed into a 500 mL round-bottom flask. WebBenzocaine is the ethyl ester of 4-aminobenzoic acid (2.3.1). The classic, optimal way of benzocaine synthesis is the reduction of the nitro group of the ethyl ester of 4-nitrobenzoic acid to benzocaine by hydrogen, which generates directly in the reaction medium by the reaction of iron filings with dilute acids [24–26].
