Reaction Steps

A flask with stirbar was charged with 2,5-dioxopyrrolidin-1-yl 3-oxobutanoate (6.47 g, 32.5 mmol), methyl 3-(4-methoxybenzylamino)propanoate (prepared as described in Bew, S. et al, Chem Commun. 2006 (41), 4338-40, 7.7 g, 34.5 mmol) and triethylamine (5 mL, 35.9 mmol) in dichloromethane (125 mL). The solution was stirred overnight at ambient temperature, then shaken in a separatory funnel with saturated aqueous sodium chloride. The organics were then washed with saturated aqueous sodium chloride containing 0.1M HCl and dried over anhydrous sodium sulfate. Filtration and solvent removal provided the title compound.
