실험 절차

A solution of ethyl 6-bromo-1-{2-[(methylsulfonyl)oxy]ethyl}-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate (Intermediate 20, 700 mg, 1.67 mmol) in dichloromethane was purged with N,N-dimethylethane-1,2-diamine gas until the starting material disappeared. The reaction mixture was washed with water, and the organic layer was dried over anhydrous sodium sulphate and concentrated under reduced pressure to afford ethyl 6-bromo-1-[2-(dimethylamino)ethyl]-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate 300 mg, (49%).
