Reaction Steps

To 3-bromo-5-(piperidin-4-yl)pyrazin-2-amine (50 mg, 0.194 mmol) in DCM (2 mL) in ice bath was added DIEA (340 μl, 1.945 mmol) and methanesulfonyl chloride (16.67 μl, 0.214 mmol). The reaction mixture was stirred for 60 min. The reaction mixture was extracted with DCM. The organic layer was washed with brine, dried over sodium sulfate, filtered and evaporated in vacuo. (30 mg, 46%). LCMS (m/z): 335.2/337.2 (MH+), 0.572 min.
