131.1 3-chloro-5-methoxypyridazine To a solution of 3,5-dichloropyridazine (300 mg) in MeOH (2 mL) was added a 5.4 M solution of sodium methoxide in MeOH (0.410 mL) and the reaction mixture was stirred for 1 h at 90 C. It was quenched with H2O and extracted with EtOAc. The organic phase was washed with a 5% solution of KHSO4, a sat. solution of NaHCO3 and brine, dried over MgSO4 and concentrated in vacuo to give the crude titled compound as an orange solid. 1H NMR ((CD3)2SO) delta: 9.01 (d, J=2.4 Hz, 1H), 7.55 (d, J=2.4 Hz, 1H), 3.96 (s, 3H), 1837-55-4
As the paragraph descriping shows that 1837-55-4 is playing an increasingly important role.
