141-30-0, 3,6-Dichloropyridazine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
In a microwave vial were mixed: 1,1-dimethylethyl 1-piperazinecarboxylate (135 mg, 0.725 mmol, available from Fluke), 3,6-dichloropyridazine (90 mg, 0.604 mmol, available from Alfa Aesar) and DIPEA (0.137 mL, 0.785 mmol) in Tert-Butanol (2 mL). The reaction was stirred and heated in an Emrys Optimizer microwave at 100 C. for 20 mins then for 30 mins at 150 C. The reaction mixture was partitioned between EtOAc (20 mL) and water (20 mL) and the organic layer washed with brine (20 mL) before being dried through an hydrophobic frit and concentrated. The residue was dissolved in DCM and purified by SP4 on a 12+M silica cartridge using a gradient of 10-50% EtOAc in cyclohexane. The appropriate fractions were collected and concentrated to yield the desired product as a white solid, 1,1-dimethylethyl 4-(6-chloro-3-pyridazinyl)-1-piperazinecarboxylate (114.2 mg). LCMS (Method C): Rt=0.85, MH+=299
141-30-0, 141-30-0 3,6-Dichloropyridazine 67331, apyridazine compound, is more and more widely used in various fields.
