Procedure

Oxone (5902 mg, 9.60 mmol) was added to a solution of (2R,4S,4aS)-11-fluoro-2,4-dimethyl-8-(2-(methylthio)pyrimidin-4-yl)-2,4,4a,6-tetrahydro-1H,1′H-spiro[isoxazolo[4,5-g][1,4]oxazino[4,3-a]quinoline-5,5′-pyrimidine]-2′,4′,6′(3′H)-trione (Example 168, 984 mg, 1.92 mmol) in MeOH:THF:H2O (30 ml)(1:1:1), and the mixture was stirred at room temperature for 48 hours. The reaction mixture was diluted with DCM (50 ml), stirred for 10 minutes, filtered, and the filter cake was washed with EtOH. The filtrate was washed with water and brine, concentrated under reduced pressure to give the desired product used in subsequent reactions without further purification.
