A suspension of 5-(1-isopropyl-6-oxo-1,6-dihydro-3-pyridazinyl)-6-phenyl-2,3-pyrazinedicarbonitrile (100 mg) in a 2M solution of ammonia in MeOH (3 ml) was stirred at 25-35° C. for 30 hours in a sealed tube. The mixture was concentrated under reduced pressure and subjected to column chromatography on silica gel eluting with a mixture of n-hexane and EtOAc (60:40 v/v) to give 6-(1-isopropyl-6-oxo-1,6-dihydro-3-pyridazinyl)-3-methoxy-5-phenyl-2-pyrazinecarbonitrile as a solid (32 mg).
