141-30-0, 3,6-Dichloropyridazine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,141-30-0
Example 2. 6-4-f4- (5-Chloro-lH-indole-2-sulphonyl)-piperazine-l-carbonvl]-phenyl}-2- (2-dimethylamino-ethvl)-2H-pyridazin-3-one Step A. To a microwave vial was added 3,6-dichloropyridazine (645mg, 4.33mmol), potassium acetate (425 mg, 4.33 mmol) and 9 mL acetic acid/water (5: 1). The reaction mixture was heated at 140 C for 70 minutes. The solvent was evaporated and the crude was purified by preparative HPLC using a gradient of acetonitrile/5 % acetonitrile- water phase containing 0.1 M ammonium acetate, to give 436 mg of 6-chloro-2H- pyridazin-3-one (77 % yield). 1H NMR (400 MHz ; methanol-d4 as solvent and internal reference) delta (ppm) 6.96 (d, 1H), 7.45 (d, 1H).
As the paragraph descriping shows that 141-30-0 is playing an increasingly important role.
