Reaction Steps
In a 100 ml RB flask was added ethyl 1-amino-1H-imidazole-2-carboxylate (0.4 g, 2.58 mmol) from (1a), DCE (12.0 mL), 2-cyanoacetyl chloride (0.320 g, 3.09 mmol) and pyridine (0.417 mL, 5.16 mmol). The resulting mixture was stirred overnight under nitrogen at room temperature. The reaction was concentrated and diluted with ethyl acetate and washed with water (2×), then the aqueous was back-extracted with ethyl acetate. The organics were collected, washed with brine, dried over Na2SO4, filtered and concentrated in vacuo to provide ethyl 1-(2-cyanoacetamido)-1H-imidazole-2-carboxylate (0.38 g, 66.3% yield).
