実験手順

Ethyl 2-(methylamino)-1,8-naphthyridine-3-carboxylate (58 mg, 0.25 mmol) was dissolved in EtOH. NaOH (0.75 ml, 1M aqueous solution) was added to the solution and the mixture stirred at 40° C. for 5.0 h. The organic solvent was removed under vacuo. The remaining aqueous residue was treated with HCl (1M aqueous solution) until slightly acidic and the product extracted with EtOAc. The combined organic phases were dried over MgSO4, filtered and concentrated yielding 50.0 mg (quant) of the title compound.
