Participants

Reaction Steps

In methanol (5 ml) was dissolved 1-[4-(4-chloro-benzoyl)benzyl]-4-chloro-6-methylimidazo[4,5-d]pyridazin-7(6H)-one (72 mg) followed by addition of 28% sodium methoxide/methanol (1.0 ml), and the mixture was refluxed for 5 hours. To this reaction mixture was added a large quantity of water and the resulting crystals were rinsed with water and dried under reduced pressure to provide 50 mg (yield 70%) of the title compound. 1H-NMR (CD3OD) δ: 3.7.1(3H,s), 4.00(3H,s), 5.85(2H,s), 7.50(2H,d,J=8.6Hz), 7.52(2H,d,J=8.8Hz), 7.74(2H,d,J=8.8Hz), 7.75(2H,d,J=8.6Hz), 8.42(1H,s).
