Participants

Reaction Steps

To a solution of 2,4-difluorobenzylamine (3.58 g, 25.0 mmol) in methylene chloride (250 mL) were added 4-ethylbenzoic acid (3.94 g, 26.3 mmol) and DMAP (3.36 g, 27.5 mmol) followed by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (5.27 g, 27.5 mmol) and the reaction mixture was stirred at room temperature overnight. The resulting solution was washed with 5% HCl (3×100 mL), saturated aqueous NaHCO3 (100 mL), and brine (100 mL) and dried over Na2SO4. Concentration in vacuo afforded 6.49 g (94%) of white solid.
