Procedure

(1-Butyl-2-oxo-1,2,5,6,7,8-hexahydroquinolin-3-yl)carbamic acid benzyl ester (6-007) (100 mg, 0.28 mmol) was dissolved in methanol (7 mL), and to the reaction mixture were added acetic acid (16 μL, 0.28 mmol) and palladium on carbon (10%, 30 mg), and the reaction mixture was stirred vigorously under hydrogen atmosphere for 1.5 h. Palladium on carbon was filtered off, and the filtrate was concentrated under reduced pressure, and the crystalloid residue was recrystallized from hexane to give 3-amino-1-butyl-5,6,7,8-tetrahydro-1H-quinolin-2-one acetic acid salt (6-001-01) (60 mg, 76%) as a white crystal.
