3,6-Dibromo-2-pyrazinecarboxylic acid Use and Manufacturing

A solution of LiOH (121 mg, 5.07 mmol) in water (1 mL) was slowly added to a solution the pyrazine ester (500 mg, 1.67 mmol) in 1:1 THF/water (8 mL) at 0° C. After stirring at 0° C. for 45 min. The solvent was removed under reduced pressure. The residue was dissolved in a mixture of DCM and 1N aq. HCl. The organic layer was separated and the aqueous extracted twice with DCM. The combined organic extracts were dried (Na
