Butyl cis(+/-)-2-(4-{[(benzyloxy)carbonyl]amino}-3-ethoxypiperidin-1-yl)-5-ethyl-1,3-oxazole-4-carboxylate → Butyl cis(+/-)-2-(4-amino-3-ethoxypiperidin-1-yl)-5-ethyl-1,3-oxazole-4-carboxylate

Participants

Reaction Steps

The same operation as in Example (95b) was performed using butyl cis(±)-2-(4-{[(benzyloxy)carbonyl]amino}-3-ethoxypiperidin-1-yl)-5-ethyl-1,3-oxazole-4-carboxylate obtained in Example (115a) (1.21 g, 2.5 mmol), 10% Pd/C (0.25 g) and methanol (15 mL), to obtain 0.89 g of the title compound as a light brown oily substance (97%).
