実験手順
1-(Aminooxy)ethane hydrochloride (23 mg, 0.23 mmol) was added to a solution of (E)-6-(3-(3-acetylazetidin-1-yl)-3-oxoprop-1-enyl)-3,4-dihydro-1,8-naphthyridin-2(1H)-one (50.0 mg, 0.16 mmol) in a mixture methanol/dichloromethane (8:2, 3.5 mL) at room temperature. The reaction mixture was stirred overnight. After concentration to dryness, the residue was purified by chromatography on silica gel using ethyl acetate/methanol (95:5) as eluent. The title product was obtained as a white solid (20 mg, 35%).
