Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 943541-20-6, name is 3-Chloro-6-(1-methyl-1H-pyrazol-4-yl)pyridazine, A new synthetic method of this compound is introduced below., SDS of cas: 943541-20-6
A mixture of 3-chloro-6-(1-methyl-1H-pyrazol-4-yl)pyridazine (494 mg, 2.5 mmol) in AcOH (20 mL) was stirred at 120 C for 4 h. The reaction mixture was concentrated under reduced pressure, and water was added to the concentrates. The generated solids was filtered and dried to afford 6-(1-methyl-1H-pyrazol-4-yl)pyridazin-3(2H)-one (431 mg, 98 %). 6-(1-Methyl-1H-pyrazol-4-yl)pyridazin-3(2H)-one (2a) 1HNMR (300 MHz, CDCl3) delta 8.70 (d, J = 11.3 Hz, 1H), 7.96(s, 1H), 6.94 (s, 1H), 6.62 (d, J = 11.3 Hz, 1H), 3.95 (s, 3H).
The synthetic route of 943541-20-6 has been constantly updated, and we look forward to future research findings.
