Procedure

To a solution of 2,3-dimethoxybenzoic acid (4.55 g, 25.0 mmol) in methylene chloride (250 mL) were added heptylamine (2.78 g, 27.5 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 MgSO4. Concentration in vacuo afforded 6.81 g (98%) of a colourless oil.
