Procedure
Dissolve 5-amino-N-methyl-N-propyl-isophthalamic acid methyl ester (1.64 g, 6.55 mmol) in dichloromethane (20 mL) and add pyridine (620 mg, 6.88 mmol) and methanesulfonyl chloride (788 mg, 6.88 mmol). Stir at room temperature for 72 h, dilute with dichloromethane, wash with 0.1 N citric acid and saturated aqueous sodium chloride. Dry (magnesium sulfate) and concentrate to give the title compound as an oil.
