실험 절차

N,N,5-Trimethyl-3-oxo-4-[3-(trifluoromethyl)phenyl]-3,4-dihydropyrazine-2-carboxamide (0.14 g, 0.43 mmol) was dissolved under argon in DMF (2 ml) in a vial. N-Bromosuccinimide (0.089 g, 0.5 mmol) was added. The vial was sealed and stirred for 30 minutes. The crude mixture was purified on preparative HPLC to give 0.100 g (57%) of the title compound as a solid.
