Reaction Steps

To a solution of 2,5-dichloropyrido[3,4-b]pyrazine (580 mg, 2.90 mmol) in N,N-dimethylformamide (10 mL) was added a 0.5-M solution of sodium methoxide in methanol (6.09 mL, 3.04 mmol), and the reaction was stirred at room temperature for 5 minutes. The solution was diluted with water and extracted with ethyl acetate. The organic layer was dried with sodium sulfate, filtered and concentrated to afford the title compound (550 mg, 2.81 mmol). MS m/z=196 (M+H).
