129779-30-2, (3R,5S)-rel-tert-Butyl 3,5-dimethylpiperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
[20371 Step 2: Synthesis of (3R.5S?)-tert-butvl4-(4-((E?)-3-methoxv-3-oxoprop- 1-en-i -vl?)benzvl?)-3.5-dimethvlpiperazine- 1 -carboxvla te[20381 (3R,55)-tert-butyl 3 ,5-dimethylpiperazine- 1 -carboxylate (formula 8-i, 5.000 g, 23.332 mmol), methyl 3-(4-bromomethyl)cinamate (formula 8-4, 5.952 g, 23.332 mmol) and Cs2CO3 (15.204 g, 46.664 mmol) were mixed in acetonitrile (150 mL) at room temperature, and the mixture was heated under reflux, and then cooled to room temperature. The reaction mixture was filtered through a paper filter to remove solids, and the filtrate was concentrated under reduced pressure to remove the solvent. The concentrate was purified by column chromatography (silicon dioxide, 80 g cartridge; ethyl acetate/hexane = from 0 % to 20 %) and concentrated to afford the desired compound (6.800 g, 75.0 %) as a yellow oil.
129779-30-2, As the paragraph descriping shows that 129779-30-2 is playing an increasingly important role.
