Procedure

A mixture of 4-methyl-3-[1-(thiomorpholin-4-yl)phthalazin-6-yl]benzamide (0.6 mmol) (Method A) in 10 mL methanol/H2O (8:2) was stirred at RT was treated with oxone® monopersulfate compound (1 mmol). The mixture was stirred at 0° C.-50° C. over 1h. The mixture was quenched with 20 mL sat. N2SO3, extracted with dichloromethane (3×50 mL). The combined organic layers were dried over anhydrous Na2SO4, concentrated in vacuo and purified by silica gel chromatography eluting with 1-5% 2 M ammonia methanol in dichloromethane to give the title compound. Found MS(ES+): 381(M+H)+.
