934-98-5, 2-(4-Methylpiperazin-1-yl)ethanamine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,934-98-5
(i) 3-((4-((4-Aminonaphthalen-1-yl)oxy)pyrimidin-2-yl)amino)-5-methoxy-N-(2-(4-methylpiperazin-1-yl)ethyl)benzamideHATU (200 mg, 0.526 mmol) was added to a solution of 3-((4-((4-((tert- butoxycarbonyl)amino)naphthalen-1-yl)oxy)pyrimidin-2-yl)amino)-5-methoxybenzoic acid (see Fyfe, M. C. T. et al., WO 2014/162126; 200 mg, 0.398 mmol), 2-(4-methylpiperazin-1- yl)ethanamine (100 mg, 0.698 mmol) and Hunig’s Base (200 muIota_, 1.145 mmol) in DMF (2 mL). The reaction mixture was stirred at rt for 72h. The reaction mixture was partitioned between water (10 mL) and DCM (20 mL). The organics were separated, dried (MgSCu), filtered and evaporated to give a brown gum. This material was dissolved in IPA (2 mL) and HCI, 6N in IPA (2 mL, 12.00 mmol) was added. The reaction mixture was stirred overnight. The solvent was evaporated and the residue partitioned between sat. NaHCC>3 (10 mL) and DCM (20 mL). The organics were separated, dried (MgSO4), filtered and evaporated to afford the subtitle compound (200 mg) as a tan glass. LCMS m/z 528 (M+H)+(ES+)
The synthetic route of 934-98-5 has been constantly updated, and we look forward to future research findings.
