928025-56-3,928025-56-3, (S)-tert-Butyl 3-ethylpiperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of tert-butyl (3S)-3-ethylpiperazine-l -carboxylate (0.5 g, 2.3 mmol) and 2-amino-4,6-dichloropyrimidine-5-carbaldehyde (0.45 g) in 1,4-dioxane (8.0 mL) was added DIPEA (1.2 mL, 7.0 mmol). The reaction mixture was heated at 120C overnight in a sealed Wheaton vial, then cooled and stirred at room temperature over the weekend. The solvent was removed in vacuo, and the residue was partitioned between water and DCM. The organic layers were phase separated and concentrated in vacuo to give the title compound (0.85 g, 99%) as a yellow glass. LCMS (ES+) [M+H]+ 370, RT 1.81 minutes (method 2).
As the paragraph descriping shows that 928025-56-3 is playing an increasingly important role.
