21655-48-1, cis-2,6-Dimethylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 14 7-[(3R,5S)-3,5-dimethylpiperazin-1-yl]-2-(2-methylimidazo[1,2-b]pyridazin-6-yl)pyrido[1,2-a]pyrimidin-4-one In a sealed tube, 7-fluoro-2-(2-methylimidazo[1,2-b]pyridazin-6-yl)-4H-pyrido[1,2-a]pyrimidin-4-one (Intermediate 1; 50 mg, 0.169 mmol), and cis-2,6-dimethylpiperazine (77 mg, 0.677 mmol, 4.0 eq.) were stirred in DMSO (2 mL) at 110 C. overnight. The solvent was removed under high vacuum. The residue was taken up in CH2Cl2 and washed with an aqueous saturated solution of NaHCO3. The organic layer was separated and dried over Na2SO4 and concentrated in vacuo. The crude was purified by column chromatography (SiO2, CH2Cl2/MeOH=95/5 to 90/10) to afford the title product (41 mg, 62%) as a light yellow solid. MS m/z 390.3 [M+H+].
21655-48-1, The synthetic route of 21655-48-1 has been constantly updated, and we look forward to future research findings.
