A flask was charged with EtOH (700 ml), tert-butyl 3-(2-ethoxy-2-oxoethylidene)pyrrolidine-1-carboxylate (246 g, 965 mmol) and Pd/C (40 g). Then the flask was charged with H2 (3 L). The resulting solution was stirred overnight. The reaction mixture was filtered and concentrated to afford tert-butyl 3-(2-ethoxy-2-oxoethyl)pyrrolidine-1-carboxylate as a colorless oil.
