実験手順
A solution of methyl 6-[(1E)-3-{4-[(4-fluorophenoxy)methyl]piperidin-1-yl}-3-oxoprop-1-en-1-yl]-2-oxo-1,2,3,4-tetrahydro-1,8-naphthyridine-3-carboxylate (13 mg, 0.028 mmol) in ammonium hydroxide (33% in water, 0.5 mL) and in ammonia (2M in ethanol, 0.5 mL) was stirred at 90° C. for 1 h30. The mixture was concentrated to dryness and the residue was purified on preparative TLC (eluent: dichloromethane/MeOH 90/10) to give 6-[(1E)-3-{4-[(4-fluorophenoxy)methyl]piperidin-1-yl}-3-oxoprop-1-en-1-yl]-2-oxo-1,2,3,4-tetrahydro-1,8-naphthyridine-3-carboxamide (1.6 mg, 12%) as a white solid.
