Procedure

Stir a solution of 5-(methyl-propylcarbamoyl)-isophthalic acid monoethyl ester (146 mg, 0.5 mmol), 1-hydroxybenzotriazole (74 mg, 0.55 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (110 mg, 0.55 mmol), ethylamine (2 N in THF, 0.275 mL, 0.55 mmol) in 0.75 mL DMF at room temperature overnight. Dilute with dichloromethane (15 mL) and wash with water (5 mL), 0.1 N aqueous citric acid (5 mL), saturated aqueous sodium bicarbonate (5 mL), and saturated aqueous sodium chloride (5 mL). Dry (magnesium sulfate) and concentrate to give the title compound (157 mg, 100%).
