Procedure

Ethyl 2-(6-chloropyrazin-2-ylamino)acetate (23.6 g, 109 mmol) was dissolved in non-denatured ethanol (250 mL) and potassium carbonate (15.13 g, 109 mmol) was added. The reaction was put under nitrogen and palladium hydroxide (3.84 g, 5.47 mmol) was added. The reaction was stirred under an atmosphere of hydrogen for 18 h. Additional palladium hydroxide (3.84 g, 5.47 mmol) was added and the reaction was charged with additional hydrogen and allowed to stir overnight. The reaction was filtered through Celite and the solvent was removed under reduced pressure to afford the title compound (15.13 g, 84 mmol, 76% yield). MS (ESI) m/z 182.3 [M+1]+.
