75336-86-6, (R)-2-Methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
75336-86-6, In a sealed tube, 2-(2,8-dimethylimidazo[l,2-b]pyridazin-6-yl)-7-fluoro-9-methyl- pyrido[l,2-a]pyrimidin-4-one (Intermediate 4; 50 mg, 0.155 mmol) and (R)-2-methylpiperazine (62 mg, 0.619 mmol, 4.0 eq.) were stirred in DMSO (2 mL) at 125C overnight. The solvent was removed under high vacuum. The residue was taken up in CH2CI2and washed with an aqueous saturated solution of NaHC03. The organic layer was separated and dried over Na2S04and concentrated in vacuo. The crude was purified by column chromatography (S1O2,CH2Cl2/MeOH=95/5 to 90/10) to afford the title product (40 mg, 70%) as a light yellow solid. MS m/z 404.3 [M+H+].
The synthetic route of 75336-86-6 has been constantly updated, and we look forward to future research findings.
