Participants

Reaction Steps

A mixture of 9-(3-chloro-4-fluorobenzyl)-7-hydroxy-3-(acetyloxymethyl)-3,4,10,11-tetrahydro[1,4]oxazino[3,4-a]-2,6-naphthyridine-1,6,8(9H)-trione (46 mg, 0.10 mmol) and 30% sodium methoxide in methanol (39 mg) in dioxane (1.5 mL) was stirred at room temperature for 2 hours. The product mixture was concentrated under vacuum. The residue was dissolved in DMSO and subjected to reverse phase column chromatography on C-18 stationary phase eluted with a 95-5% water-acetonitrile gradient. Collection and lyophilization of appropriate fractions afforded the title compound.
