Participants

Reaction Steps

A solution of 2,3-dichloropyrido[3,4-b]pyrazine (3.55 g, 17.75 mmol) in dioxane (71.0 mL) at room temperature was treated with cyclopropanamine (1.63 mL, 23.07 mmol), followed by dropwise addition of DIPEA (6.51 mL, 37.3 mmol). The resulting reaction mixture was stirred at room temperature for 12 h. Purification by flash silica gel chromatography using a gradient of 25% to 100% EtOAc in hexanes gave the title compound (3.15 g, 80%) as an orange solid. ESI-MS m/z [M+H]+ 221.1.
