Reaction Steps

Under N2, to a solution of (S)-(1-(7-(4-morpholinophenyl)pyrido[4,3-b]pyrazin-5-yl)pyrrolidin-3-yl)methanamine (Compound 77, 51 mg, 0.13 mmol) and Et3N (0.04 mL, 0.26 mmol) in anhydrous THF (3 mL) was added MsCl (30 mg, 0.26 mmol) at 0° C. The reaction mixture was stirred at ambient temperature for 0.5 hour, then quenched with H2O and extracted with EtOAc. The combined extracts were dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by preparative thin-layer chromatography to afford the title compound. MS (m/z): 469 (M+H)+.
