Step C: N-(6-Chloro-4-pyridazinyl)-N’-(1-methylethyl)urea To a stirred solution of 0.8 gram of 4-amino-6-chloro-pyridazine in 30 ml of dimethylformamide is added 0.2 gram of 1,4-diazabicyclo[2.2.2]octane, followed by 0.6 gram of 1-methylethyl isocyanate. The reaction mixture is stirred at ambient temperature for 18 hours, then at 60 C. for six hours. The majority of the dimethylformamide is removed under reduced pressure, and the residue is slurried in water. The resultant solid is collected by filtration and dried to yield N-(6-chloro-4-pyridazinyl)-N’-(1-methylethyl)urea., 29049-45-4

Synthetic Route of 141-30-0, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.141-30-0, Name is 3,6-Dichloropyridazine, molecular formula is C4H2Cl2N2. In a Article，once mentioned of 141-30-0

A series of 2-substituted-6-(morpholinyl/piperidinyl)pyridazin-3(2H)-ones was synthesized and the structures were established using various spectroscopic techniques. The target compounds were screened for anti-inflammatory and analgesic activities at 20 and 40 mg/kg. The safety of the synthesized derivatives was evaluated by assessing anti-platelet activity and ulcer index. The obtained pharmacological data revealed that 6-morpholinyl derivatives 4a?12a were found to be somewhat more potent than 6-piperidinyl derivatives 4b?6b. The 6-morpholinyl substituted pyridazinone 12a exhibited maximum anti-inflammatory and analgesic activities. Homoveratrylamine substituted compounds 6a and 6b emerged as promising leads in both the series with good anti-inflammatory and analgesic activities without any ulcerogenicity. Anti-platelet activity results of the compounds of both the series showed significantly low bleeding time in comparison with standard drug aspirin indicating the cardiovascular safety of new pyridazinones.
