Reaction Steps

A mixture of 6-(5-amino-6-bromo-3-phenyl-2-pyrazinyl)-2-methyl-3(2H)-pyridazinone (150 mg) and benzylamine (0.138 ml) in DMA (0.3 ml) was heated at 120-125° C. for 50 hours. After addition of water (4 ml), an aqueous layer was removed by decantation to give a residue. The residue was dissolved in CHCl3, dried over MgSO4, concentrated under reduced pressure and purified by column chromatography on silica gel. By elution with a mixture of n-hexane and EtOAc (60:40 v/v) was obtained 6-[5-amino-6-(dimethylamino)-3-phenyl-2-pyrazinyl]-2-methyl-3(2H)-pyridazinone as a solid (83 mg) and by elution with a mixture of n-hexane and EtOAc (20:80 v/v) was obtained 6-[5-amino-6-(benzylamino)-3-phenyl-2-pyrazinyl]-2-methyl-3(2H)-pyridazinone as a solid (48 mg).
