Reaction Steps

3-Benzyloxycarbonylamino-1-butyl-5,6-dimethyl-2-pyridone (5-017) (2.487 g) was dissolved in methanol (25 mL), and to the reaction mixture was added a suspension of 10% palladium on carbon (373 mg) in water (2.5 mL), and the reaction mixture was reacted in catalytic reduction under atmospheric pressure. After 4 h, the reaction mixture filtered off on Celite, washed with methanol, and evaporated under reduced pressure to give 3-amino-1-butyl-5,6-dimethyl-2-pyridone (5-004-02) (1.438 g, 97.8%, m.p. 94 to 97° C.) as a brown crystal.
