Reaction Steps

The same operation as in Example (95b) was performed using ethyl cis(±)-2-(4-{[(benzyloxy)carbonyl]amino}-3-methoxypiperidin-1-yl)-4-methyl-1,3-oxazole-5-carboxylate obtained in Example (107a) (0.32 g, 0.77 mmol), 10% Pd/C (0.3 g), ethyl acetate (3 mL) and methanol (3 mL), to obtain 0.22 g of the title compound as a brown oily substance (100%).
