To a solution of tert-butyl 2-((7-(4-morpholinophenyl)pyrido[4,3-b]pyrazin-5-ylamino)methyl)thiomorpholine-4-carboxylate (178 mg, 0.34 mmol) in CH2Cl2 (5 mL) was added 3-chloroperoxybenzoic acid (70%, 251 mg, 1.02 mmol) at 0° C. The resulting mixture was stirred at room temperature for 3 hours, and subsequently, a saturated aqueous sodium thiosulfate solution was added and the mixture was stirred for another 30 minutes. The layers were separated and the aqueous layer was extracted twice with EtOAc. The combined EtOAc layers were washed twice with an aqueous Na2CO3 solution. The combined organic layers were dried (Na2SO4), filtered and concentrated in vacuo to afford title compound 52 mg. MS (m/z): 555 (M+H)+
