Procedure
To a solution of (3-cyano-phenyl)-acetic acid methyl ester (18.06 g, 103 mmol) in MeOH (150 mL) and 4M HCl in dioxane (30.0 mL, 120 mmol) was added 10% palladium on carbon (2 g). The mixture was placed on a Parr shaker and was hydrogenated at 50 psi hydrogen for 24 h. The catalyst was removed via filtration through Celite® and the organic solution was concentrated in vacuo. The resulting solid was stirred in EtOAc and filtered to provide the title compound as a white solid (20.42 g). 1H NMR (400 MHz, CD3OD) δ 7.42-7.32 (m, 4H), 4.09 (s, 2H), 3.69 (s, 2H), 3.67 (s, 3H); MS 180 (M+1). mg).
