Procedure

Oxone (0.88 g, 1.4 mmol) was added in one portion to a stirred solution of 2-isopropyl-4-(5-methyl-1H-pyrazol-3-ylamino)-7-methylsulfanyl-2H-phthalazin-1-one (0.12 g, 0.36 mmol) in a 4:1 mixture of dioxane/water (1.2 ml) and the reaction mixture was stirred at room temperature for one hour. The reaction mixture was diluted with water (5 ml) and the solution was extracted with ethyl acetate (3×75 ml), the organic layers were combined, dried (MgSO4), filtered and concentrated under vacuum to give a dark brown solid. Flash column chromatography (elution: 96% DCM, 4% methanol) gave the title compound (0.032 g, 25% yield) as a light yellow solid (Example H-2).
