A solution of 3-amino-5-(2-bromophenyl)-6-(1-isopropyl-6-oxo-1,6-dihydro-3-pyridazinyl)-2-pyrazinecarboxamide (695 mg) in a mixture of 5N aq. NaOH (4 ml) and EtOH (4 ml) was refluxed for 4 hours. After removal of EtOH by evaporation, the mixture was adjusted to pH 4 with 1N HCl to give a precipitate. The precipitate was collected by filtration and dried under reduced pressure to give 3-amino-5-(2-bromophenyl)-6-(1-isopropyl-6-oxo-1,6-dihydro-3-pyridazinyl)-2-pyrazinecarboxylic acid (664 mg).
