실험 절차

To a solution of 3-amino-5-trifluoromethyl-pyrazine-2-carboxylic acid ethyl ester (Intermediate B) (30 mg, 0.13 mmol) in acetic acid (5 ml), sodium carbonate (15 mg, 0.14 mmol) was added. To this mixture, half the contents of a solution of bromine (7 μL, 0.13 mmol) in acetic acid (5 ml) were added, followed by the addition of sodium carbonate ((15 mg, 0.14 mmol). The remaining solution of bromine in acetic acid was added and the reaction mixture was left to stir at RT for 2 hours. The mixture was diluted with water and the resulting yellow precipitate was filtered under vacuum to afford the title compound.
