To the suspension of 3-methoxy-4-nitrobenzonitrile (11.4 g, 64 mmol) in ethyl acetate (60 mL) was added 10% Pd/C (1 g). The reaction mixture was vigorously shaken in a Parr under an atmosphere of hydrogen (50 psi) at room temperature for 45 min. The mixture was filtered through a short pad of celite, and the filtrate was concentrated to give 4-amino-3-methoxy-benzonitrile as a yellow oil, which solidified at stand (9.5 g, 95%)
