74879-18-8, (S)-(+)-2-Methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 11 2-(2-methylimidazo[l,2-b]pyridazin-6-yl)-7-[(3S)-3-methylpiperazin-l-yl]pyrido[l,2- a]pyrimidin-4-one In a sealed tube, 7-fluoro-2-(2-methylimidazo[l,2-b]pyridazin-6-yl)-4H-pyrido[l,2- a]pyrimidin-4-one (Intermediate 1; 50 mg, 0.169 mmol), and (S)-2-methylpiperazine (68 mg, 0.677 mmol, 4.0 eq.) were stirred in DMSO (2 mL) at 110C overnight. The solvent was removed under high vacuum. The residue was taken up in CH2CI2 and washed with an aqueous saturated solution of NaHC03. The organic layer was separated and dried over Na2S04 and 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, 63%) as a light yellow solid. MS m/z 376.2 [M+H+]., 74879-18-8
As the paragraph descriping shows that 74879-18-8 is playing an increasingly important role.
