Reaction Steps

5-Methyl-N-{[5-(methylsulfonyl)-pyridin-2-yl]methyl}-3-oxo-4-[3-(trifluoromethyl)phenyl]-3,4-dihydropyrazine-2-carboxamide (0.097 g, 0.21 mmol) was dissolved in DMF (2 ml) in a vial. To this mixture was added N-bromosuccinimide (0.055 g, 0.31 mmol), and the vial was sealed and the mixture was heated at 50° C. with stirring for 1 h. The crude mixture was added dropwise to water (40 ml) under magnetic stirring. The precipitate was isolated by filtration to give 0.105 g (92%) of 6-bromo-5-methyl-N-{[5-(methylsulfonyl)pyridin-2-yl]methyl}-3-oxo-4-[3-(trifluoromethyl)phenyl]-3,4-dihydropyrazine-2-carboxamide as a solid.
