5096-73-1, 6-Chloropyridazine-3-carboxylic acid is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,5096-73-1
Step 1: To a mixture of compound 7-1 (4.14 g, 26.1 mmol) in DCM (100 mL) was added oxalyl chloride (3.98 g, 31.3 mmol) dropwise. DMF (0.05 mL) was added and the resulting mixture was stirred at room temperature until the compound 7-1 was dissolved. Then MeOH (2 mL) was added dropwise and stirred for another 0.5 hr. After being washed with brine (100 mL), the mixture was dried over anhydrous Na2SC>4 and concentrated to give crude product. The crude product was purified by silica-gel column chromatography (eluting with PE/EA = 4/1) to yield the desired product 7-2 as white solid. LC-MS: m/z = 173.1
As the paragraph descriping shows that 5096-73-1 is playing an increasingly important role.
