Reaction Steps

A solution of (S)—N-((4-(methylsulfonyl)morpholin-2-yl)methyl)-7-(4-(piperazin-1-yl)phenyl)pyrido[4,3-b]pyrazin-5-amine (60 mg, 0.12 mmol), Formalin (48 mg, 0.48 mmol) and NaBH(AcO)3 in 5 mL of DCM, was stirred at room temperature for 2 hours. The volatiles were removed in vacuo, and the residue was purified by chromatography with MeOH/H2O (1:10˜10:1) to give 46 mg of title compound. MS (m/z)=498 (M+H)+.
