Step 3: Fischer esterification with benzoic acid gives hexylcaine (Section 17.7). Note that the acid chloride method can not be used here because of secondary amine of the -aminoalcohol is a stronger nucleophile that the hydroxyl group. Problem 23.64 Following is an outline for a synthesis of the anorexic (appetite suppressant) fenfluramine.

Weigh the 4-(bromomethyl)benzoic acid and calculate the percentage yield (MW: 215.0). Make sure to determine the limiting reagent in your calculation section in your lab report. ... Attach an IR and NMR of the product with all of the peaks labeled. For IR you need to find the C-H stretches, OH stretch on the carboxylic acid and the C=C stretch ...

Benzoic acid is soluble in most organic solvents including dichloromethane and ether. However, this acid can be easily deprotonated with base to give a charged ionic species that is readily soluble in water. By converting benzoic acid to the sodium salt of benzoic acid, the solubility has drastically changed.

Isolation of the Benzoic Acid. To the aqueous alkaline solution, separated and set aside, add 6 M HCl dropwise until the solution is distinctly acidic to litmus paper. Cool the flask in an ice bath for about 10 minutes. Collect the precipitated benzoic acid by reduced pressure filtration using a Hirsch funnel.
