Reaction Steps

To a solution of methyl 2-amino-4-chlorobenzoate (18.60 g, 100 mmol) and pyridine (11.5 ml, 142 mmol) in toluene (138 ml), was added dropwise a solution of ethyl succinyl chloride (18.9 ml, 133 mmol) in toluene (19 ml) at a temperature between 0° C. and 10° C. The mixture was stirred at 10° C. for 1 hr, water was added and the mixture was extracted with ethyl acetate. The organic layer was successively washed with 0.1N hydrochloric acid and 10% aqueous sodium hydrogen carbonate solution and dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure to give methyl 4-chloro-2-(3-ethoxycarbonylpropionylamino)benzoate (27.90 g, yield 89%).
