Reaction Conditions

Reaction Steps

To 2,6-dichloropyrazine (50 g, 336 mmol) and ethyl 2-aminoacetate (34.6 g, 336 mmol) was added triethylamine (140 mL, 1007 mmol) and acetonitrile (350 mL). The reaction was heated at 80° C. for 3 d. Precipitated triethylamine salts were removed by filtration and washed with ethyl acetate and hexane (1:1) multiple times. The filtrate and wash solvent were combined and concentrated. The resulting white-yellow precipitate was filtered and washed with 20% ethyl acetate in hexane to afford an off-white solid. The filtrate was subjected to the same process to give an additional batch of off-yellow solid. The batches were combined to afford the title compound (35.5 g, 164 mmol, 49% yield). MS (ESI) m/z 216.1 [M+1]+.
