Reaction Steps

To a stirred suspension of tert-butyl 3-{2-amino-6-[2-(benzyloxy)phenyl]-3-cyano-4-pyridinyl}-1-piperidinecarboxylate (0.300 g, 0.619 mmol), which was obtained in the step (1) of Example 1-1, in ethanol (10 mL) was added a solution of potassium hydroxide (0.695 g, 12.381 mmol) in ethanol (20 mL). The reaction mixture was stirred at 70° C. for 60 hrs. After cooled to room temperature, the reaction mixture was poured into water and the resulting solid was filtrated and dried under reduced pressure to give tert-butyl 3-{2-amino-6-[2-(benzyloxy)phenyl]-3-carbamoyl-4-pyridinyl}-1-piperidinecarboxylat as a white amorphous. (0.226 g, yield; 73%).
