Acetic Acid → (3-Amino-6-bromo-5-methylpyrazin-2-yl)(phenyl)methanone

Participants

Reaction Steps

Potassium carbonate (0.23 g, 1.64 mmol) is dissolved in glacial acetic acid (5 ml, 1.64 mmol) and (3-amino-5-methyl-pyrazin-2-yl)-phenyl-methanone (0.17 g, 0.82 mmol) and bromine (0.055 ml, 1.07 mmol) are added. The resulting yellow solution is stirred at room temperature for 1.5 hours. The solvent is removed in vacuo, and the residue is suspended in DCM, filtered and washed with DCM. The filtrated is concentrated and dried in vacuo to yield the title compound as a yellow solid. [M+H]+ 292.
