Versuchsvorschrift
To a solution of 5-aminopyrazine-2-carbonitrile (5-1) (350 mg, 2.92 mmol) in ethanol (15 mL) was added 2-chloroacetaldehyde (4 mL, 40% in water). The mixture was stirred at 110° C. overnight. The solution was concentrated, then purified by chromatography on silica gel to afford the title compound (280 mg). MS (m/z): 145.1 (M+H)+.
