실험 절차

The same operation as in Example (90d) was performed using tert-butyl cis(±)-4-(benzylamino)-3-ethoxypiperidine-1-carboxylate obtained in Example (112c) (4.06 g, 12.1 mmol), 10% Pd/C (wet, 1.1 g), ammonium formate (2.87 g, 46 mmol) and methanol (30 mL), to obtain 2.28 g of the title compound as a colorless oily substance (94%).
