To 4-(Aminomethyl)benzoic acid (0.2 g, 1.32 mmol) was added in NMP (5 mL). Hexadecanedioic acid tert-butyl ester 2,5-dioxo-pyrrolidin-1-yl ester (0.58 g, 1.32 mmol) was added and the mixture was stirred at room temperature overnight. The mixture was poured into water (100 mL), the precipitate was isolated by filtration and dried in vacuo. The crude material was recrystallized from toluene to give 4-[(15-tert-butoxycarbonylpentadecanoylamino)methyl]benzoic acid (413 mg).
