[1194] To a solution of ethyl pyrrolo[1,2-a]pyrazine-3-carboxylate (0.60 g, 3.18 mmol) in CH2Cl2 (60 mL) is added N-bromosuccinimide (0.56 g, 3.18 mmol) in one portion. After 1 h, solvent is removed in vacuo and the crude solid purified using preparative HPLC (1% IPA/heptane (0-5 minutes) to 2% isocratic) to give a brown solid for ethyl 6-bromopyrrolo[1,2-a]pyrazine-3-carboxylate. Yield 57%. MS (ESI+) for C10H9BrN2O2 m/z 271.01 (M+H)+.
