Versuchsvorschrift

A mixture of methyl 3-aminopyrazine-2-carboxylate (8.35 g, 54.53 mmol) and N-bromo-succinimide (9.705 g, 54.53 mmol) was stirred in MeCN (100 mL) at room temp overnight. The resultant precipitate was filtered, washed with MeCN and dried to give the desired product as a yellow solid (11.68 g, 92% Yield)
