Reaction Steps

A 5.4 g (0.044 mol) sample of chloroacetyl chloride was added dropwise to a solution of 9 g (0.044 mol) 3-(N-2-methoxyphenylamino)-gamma-butyrolactone and 3.8 g (0.048 mol) pyridine in 150 ml ethyl acetate at 37°-46° C. After stirring at 46° C for 15 minutes, the reaction mixture was cooled and diluted with water. The organic layer was separated, washed with 10% aqueous sodium bicarbonate, washed with water, dried over magnesium sulfate and evaporated under reduced pressure to give the product, as a colorless solid. The melting point and elemental analysis for the product is tabulated in Table I, as compound No. 3.
