Reaction Steps

A mixture of methyl 5-chloropyrazine-2-carboxylate (0.75 g), K2CO3 (1.8 g) and 2-methyl-1H-imidazole (1.3 g) in N,N-dimethylformamide (6 mL) is heated to 100° C. overnight. Analysis of the crude mixture by LCMS shows saponified product. The solvents are evaporated and the crude product is purified by HPLC. LC (method 20): tR=0.27 min; Mass spectrum (APCI): m/z=205 [M+H]+.
