Reaction Steps

Combined 2,3-dichloropyrido[3,4-b]pyrazine (1 g, 5.00 mmol) and DIPEA (1.75 mL, 10.00 mmol) in DCM (10.00 mL) and cooled to 0° C. and added tert-butylamine (1.590 mL, 15.00 mmol) and stirred for 48 h. The reaction mixture was poured into saturated aqueous NH4Cl and extracted twice with EtOAc. The organic extracts were combined, filtered through MgSO4, and concentrated in vacuo. The residue was redissolved in EtOAc, filtered through a one inch plug of silica, washing with EtOAc, and concentrated gave N-(tert-butyl)-3-chloropyrido[3,4-b]pyrazin-2-amine (1.04 g, 88%).
