5-BROMOPYRAZINE-2-CARBONITRILE Use and Manufacturing
ii) 5-Aminopyrazine-2-carbonitrile (0.208 mmol) in acetonitrile (1 mL) was added portionwise to a stirred solution of copper (II) bromide (0.25 mmol) and t-butylnitrite (0.31 mmol) in acetonitrile (2 mL) and the reaction mixture was maintained at 60 ° C. for 1 h. The reaction was diluted with ethyl acetate (15 mL) and washed twice with 1N HCl (aqueous). Purification was done by chromatography (silica, hexane; ethyl acetate) to yield the title compound (49percent). In a dry flask under argon was added
