YieldReaction ConditionsOperation in experiment
In ethanol for 16h; Reflux; 60 Example 607-Benzyl-l-cyano-4-hydroxy-8-oxo-7,8-dihydro- [2,7] naphthyridine-3-carboxylic acid(pyridazin-4-ylmethyl)-amide[0325] A mixture of 7-benzyl-l-cyano-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3- carboxylic acid methyl ester (25 mg, 0.075 mmol) and pyridazin-4-yl-methylamine (29 mg, 0.26 mmol) in EtOH (2 mL) was refluxed for 16 h. AcOH (0.1 mL) and water (2 mL) were added, and the mixture was allowed to come to r.t. The resulting suspension was filtered and the solid was washed with 5 mL of MeOH/H20 (1 :1). The solid was dried under vacuum to give 22 mg of the title compound. MS: (+) m/z 413.30 (M+l).
