16401-70-0, N-Methylpyridazin-4-amine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,16401-70-0
600 mg (2.8 mmol) of S-tert-Butylcarbamoyl-isoxazole^-carboxylic acid were suspended in 20 ml. of toluene and two drops of dimethylformamide were added to the mixture. 0.26 ml. of thionylchloride (3.5 mmol) were added at room temperature and the reaction mixture was stirred at 65 0C for two hours. After removal of the solvent, toluene was added and the evaporation was repeated. The obtained residue was then dissolved in 10 ml. of dichloromethane and the solution was added dropwise to a solution containing 247 mg methyl-pyridazin-4-ylamine (2.3 mmol) and 0.43 ml triethyl amine (3.1 mmol) in 40 ml dichloromethane. The mixture was stirred at room temperature for 16 h and the solvent was removed under vaccum. The obtained residue was purified by flash column chromatography (silica, gradient elution cyclohexane? ethyl acetate? methanol) to give 180 mg (20%, 95% purity) of the title compound.
16401-70-0 N-Methylpyridazin-4-amine 23080684, apyridazine compound, is more and more widely used in various.
