With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.141-30-0,3,6-Dichloropyridazine,as a common compound, the synthetic route is as follows.
Intermediate L6-((6-Chloro-[1 ,2,4]triazolo[4,3-b]pyridazin-3-yl)methyl)quinoline Acetic acid, 500C 3-Chloro-6-hydrazinylpyridazine (i) A mixture of 3,6-dichloropyridazine (3 g, 20.14 mmol) and hydrazine monohydride(1 g, 20.14 mmol) was heated in a sealed tube to 80 0C for 5 hours. Solvent was evaporated and the crude was used in the next step without purification (3.56 g, 100%). LCMS (method B): [MH]+ = 145.1 , tR = 0.57 min.
141-30-0, The synthetic route of 141-30-0 has been constantly updated, and we look forward to future research findings.
