Participants

Reaction Steps

{2-[(7-Benzyl-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3-carbonyl)-amino]-ethyl}-methyl-carbamic acid tert-butyl ester (65 mg, 0.14 mmol) was dissolved in CH2Cl2 (2 mL). Trifluoroacetic acid (1 mL) was added, and the mixture was stirred at r.t. for 2 h. Solvent and excess TFA were removed in vacuo. To the residue were added THF (5 mL), triethylamine (0.1 mL, 0.72 mmol), and ethyl formate (5 mL), and the resulting mixture was refluxed for 4 days. Mixture was concentrated in vacuo, and the residue was purified by silica gel chromatography (0-5% MeOH/CH2Cl2) to give 35 mg of the title compound as a light yellow solid. MS: (+) m/z 381.34 (M+1).
