Reaction Steps

A mixture of 7-benzyl-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3-carboxylic acid methyl ester (40 mg, 0.13 mmol), 2M NaOH (2 mL), MeOH (2 mL) and THF (1 mL) was stirred at r.t. for 4 h. 1 M HCl was added until pH was about 2, and the resulting mixture was cooled in an ice bath for 30 min. The precipitate formed was collected by filtration and dried under high vacuum to afford 23 mg of the title compound as a yellow solid. MS: (+) m/z 297.00 (M+1).
