Reaction Steps
Combine 3-cyano-3-phenylpentanedioic acid diethyl ester (243 g, 0.84 mol) and ethanol (2.5 L), concentrated aqueous ammonia (325 mL), and Raney nickel (250 g, prewashed three times with water) in a two gallon autoclave. Charge with 200 psi of hydrogen. Heat to 50° C. After 24 hours, vent the reactor and purge with nitrogen. Filter the reaction mixture through a celite pad and rinse the solids with ethanol (1 L). Evaporate the filtrate in vacuo to give the title compound.
