실험 절차

A mixture of 1-(2-bromophenyl)-2-(1-isopropyl-6-oxo-1,6-dihydro-3-pyridazinyl)-1,2-ethanedione (5.30 g) and (2Z)-2,3-diamino-2-butenedinitrile (1.65 g) in a solution of DMSO (0.25 ml) and toluene (25 ml) was refluxed for 8 hours. The mixture was concentrated under reduced pressure to give a residue. The residue was purified by column chromatography on silica gel eluting with a mixture of n-hexane and EtOAc (85:15 v/v) to give 5-(2-bromophenyl)-6-(1-isopropyl-6-oxo-1,6-dihydro-3-pyridazinyl)-2,3-pyrazinedicarbonitrile as a solid (3.58 g).
