Reaction Steps

To a solution of 3-oxo-3-phenylpropanenitrile (10 g, 68.8 mmol) and PTSA (0.027 g, 1.37 mmol) in toluene (120 mL) is added ethylene glycol (120 mL, 2057 mmol). The mixture is heated at 150° C. for 14 h. The solvent is evaporated under reduced pressure and the residue is washed with 10% NaOH solution. The aqueous layer is extracted with diethyl ether (2×100 mL) and the combined organic layers are dried (Na2SO4) and evaporated to provide the crude compound. The crude material is purified over neutral alumina eluting with 1% of ethyl acetate/hexane to afford the title compound as an off white solid (10 g, 77%).
