Reaction Steps
4-Aminomethyl)benzoic acid (3.0 g) is suspended in pyridine (15 mL) and the mixture cooled in an ice water bath. Butyric anhydride (9.2 mL) is added dropwise to the stirred suspension over a 20 min period. The ice bath is removed and the mixture stirred at room temperature overnight. The mixture is poured into 150 mL ice water and made acidic (pH 1.5) by addition of concentrated HCl. The precipitate is recovered by suction filtration and recrystallized from ethyl acetate to produce N-(4-carboxybenzyl)butyramide, m.p. 186.5°-187.5° C.
