20744-39-2, Pyridazin-4-amine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step B: N-(4-pyridazinyl)-N’-(1-methylethyl)urea To a stirred solution of 2.3 grams (0.024 mole) of 4-aminopyridazine (prepared as in Example 1, Step A) and 0.5 gram (0.004 mole) of 1,4-diazabicyclo[2.2.2]octane in 20 ml of dimethylformamide is added dropwise 3.3 ml (0.033 mole) of (1-methylethyl) isocyanate. Upon completion of addition the reaction mixture is stirred at ambient temperature for two days. The reaction mixture is concentrated under reduced pressure and the solid residue dried at 60-70 C. The solid is stirred with ethanol and collected by filtration to yield 1.9 grams of N-(4-pyridazinyl)-N’-(1-methylethyl)urea; m.p. 206-209 C. then 266-269 C. The nmr spectrum is cnsistent with the proposed structure., 20744-39-2
The synthetic route of 20744-39-2 has been constantly updated, and we look forward to future research findings.
