Procedure

To a solution of 1′-benzyl-3H-spiro[2-benzofuran-1,3′-pyrrolidine] (200 mg, 0.0008 mol) in methanol (10 mL) was added Pd/C (150 mg), and the suspension was hydrogenated under H2 (50 psi) overnight. The mixture was filtered and then concentrated to give the desired compound (110 mg, 92% yield). MS (ESI): 176.1 (M+H+).
