To a solution of compound 178 (2.0 g, 9.42 mmol, 1.0 eq.) in methanol (40 mL) was added palladium carbon (1.0 g, 0.94 mmol, 0.1 eq.). The reaction mixture was subjected to hydrogenation at atmospheric pressure and room temperature for 6 hours. After completion of the reaction, the reaction mixture was filtered through diatomaceous earth and the filtrate was concentrated under reduced pressure. The target compound (S)-1-Boc-3-aminopyrrolidine was obtained as a yellow oil (1.7 g, 97% yield).

To a solution of product 178 (2.0 g, 9.42 mmol, 1.0 eq.) in 40 mL of methanol, palladium on charcoal (1.0 g, 0.94 mmol, 0.1 eq.) is added. The reaction medium is submitted to hydrogenation at atmospheric pressure and at room temperature for 6 hours. The reaction medium is then filtered on celite and concentrated under dry conditions under reduced pressure. The expected compound is obtained as a yellow oil (1.7 g, 97%).
