Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 943541-20-6, name is 3-Chloro-6-(1-methyl-1H-pyrazol-4-yl)pyridazine, This compound has unique chemical properties. The synthetic route is as follows., Safety of 3-Chloro-6-(1-methyl-1H-pyrazol-4-yl)pyridazine
STEP 2: 6-fluoro-1-M-f6-M-methyl-1 H-Dyrazol-4-yl)Dyridazin-3-yl)DiDeridin-4- vDindoline To a mixture of 6-fluoro-1-(piperidin-4-yl)indoline (256 mg, 1 mmol), 3- chloro-6-(1-methyl-1 H-pyrazol-4-yl)pyridazine prepared as in STEP 1 above (194 mg, 1.0 mmol) in DMSO (3 mL) was added DIPEA (0.52 mL, 3 mmol). The resulting mixture was sealed and heated at 180C for 1 .5 h under microwave irradiation. The resulting mixture was poured into H20 (30 mL) and the aqueous layer was extracted with 30% CH2Cl2/Et20 (30 mL x 5). The combined organic layer was dried (Na2S04) and filtered. The solvent was removed and the resulting residue was purified by column using 90-100% EtOAc/hexane as the eluent to yield the title compound, 6-fluoro-1 -(1-(6-(1- methyl-1 H-pyrazol-4-yl)pyridazin-3-yl)piperidin-4-yl)indoline.
