Reaction Steps
Fifty milliliters of ethyl acetate were added to a solution of 4.0 g of disodium 2-(p-chlorobenzoylamino)-2-(2-cyanoethyl)malonate dihydrate in water (50 ml), and the resulting solution was adjusted to pH 2.0 by adding 1N hydrochloric acid at 0°-5° C. The organic layer was separated off and dried over magnesium sulphate. The solvent was distilled off and the resulting residue was recrystallized from diethyl ether, to give 3.2 g of the desired acid (b) as a colourless powder melting at 103°-105° C. (with decomposition).
