m-Chloroperbenzoic acid → 1-Oxo-1lambda~5~-1,5-naphthyridine

Participants

Reaction Steps

m-CPBA (1.2 g, 6.91 mmol) was added in 3 portions (after every 3 h) to a solution of 1,5-naphthyridine (1.0 g, 7.68 mmol) in dry DCM (60 ml). After completion of the reaction, the mixture was concentrated in vacuo. The crude residue was purified by column chromatography with DCM/MeOH (98:2) as the eluent to get title compound (0.85 g, 76%).
