Reference of 66346-87-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 66346-87-0, 6-Chloro-5-methylpyridazin-3-amine, introducing its new discovery.

Research on heterocyclic compounds, XLI. 2-phenylimidazo[1,2- b]pyridazine-3-acetic derivatives: Synthesis and anti-inflammatory activity

The synthesis of a group of 2-phenylimidazo[1,2-b]pyridazine-3-acetic esters and acids is described. The structures of the new compounds are supported by 1H-NMR spectra. These compounds were tested in vivo for their anti-inflammatory, analgesic and ulcerogenic activity. All new compounds showed remarkable anti-inflammatory action in the carrageenan rat paw oedema (one third of that for indomethacin) but no significant analgesic activity in the acetic acid writhing test together with negligible ulcerogenic action, and were also found to be lacking inhibitory activity on cyclooxygenase in vitro.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.66346-87-0,6-Chloro-5-methylpyridazin-3-amine,as a common compound, the synthetic route is as follows.

The reaction is performed underan argon-atmosphere. 6-Chloro-5-methylpyridazin-3-amine (3.00 g; 20.90 mmol), ie/f-butyl 4-(4,4,5,5-tetramethyl-1 ,3,2-dioxaborolan-2-yl)-1 ,2,3,6- tetrahydropyridine-1 -carboxylate (7.1 1 g; 22.98 mmol) and sodium carbonate (2 mol/L, aq. solution; 41 .79 mL; 83.58 mmol) in 1 ,4-dioxane (150 mL) is purged with argon. After 5 minutes Xphos 2nd Gen. (0.49 g; 0.63 mmol) is added and the mixture is stirred over night in a sealed vial at 100C. The reaction mixture is concentrated under reduced pressure. The residue is taken up in water and extracted several times with EtOAc. The combined organic layers are washed with brine, dried over Na2S04, filtered and concentrated under reduced pressure. The residue is purified by silica gel chromatography (DCM/MeOH). (1086) Yield: 5.20 g (86%) ESI-MS: m/z = 291 [M+H]+ Rt(HPLC): 0.79 min (method 10), 66346-87-0

The synthetic route of 66346-87-0 has been constantly updated, and we look forward to future research findings.

66346-87-0, Example 65 Preparation of Intermediate 66 [0664] [0665] A mixture of intermediate 58 (293 mg, 0.958 mmol) and 6-chloro-5-methylpyridazin-3-amine (195 mg, 1.35 mmol) in 16 mL of ethanol was heated at 77 C. overnight. After cooling to room temperature the reaction mixture was concentrated under reduced pressure and the residue was purified via silica gel column chromatography (5-100% ethyl acetate in hexanes) to yield intermediate 66 (125 mg, 38%) as a white solid.
