Reaction Steps
A solution of 2,3-dichloro-7-methylpyrido[3,4-b]pyrazine (125 mg, 0.584 mmol), 2,2-difluoroethanamine (53.6 μL, 0.701 mmol), and DIPEA (306 μL, 1.752 mmol) in DCM (1.17 mL) was stirred at room temperature for 48 h, then poured into a saturated aqueous solution of NH4Cl and extracted twice with EtOAc. The extracts were combined, filtered through MgSO4, and concentrated to give 3-chloro-N-(2,2-difluoroethyl)-7-methylpyrido[3,4-b]pyrazin-2-amine (143 mg, 95%).
