5464-12-0,5464-12-0, 1-(2-Hydroxyethyl)-4-methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A solution of triphenylphosphane (31.7966 mg, 0.121 mmol) in 1 : 1 DCM:THF (0.6 mL) was cooled to 0°C and treated with diisopropyl azodicarboxylate (0.023 mL, 0.121 mmol) and stirred at 0°C for 15 min. The reaction mixture was treated with 6-hydroxy-4-(6-(4- (pyridin-2-yloxy)piperidin-l-yl)pyridin-3-yl)pyrazolo[l,5-a]pyridine-3-carbonitrile(Intermediate P78, 25.0 mg, 0.0606 mmol) in a 1 : 1 DCM:THF (0.6 mL) and 1-(N- hydroxyethyl)-4-methyl piperazine (13.1 mg, 0.0909 mmol). The reaction mixture was allowed to warm to rt and was stirred at this temperature for 30 min. The reaction mixture was concentrated in vacuo, and the resultant crude residue was directly purified by C-18 reverse phase chromatography (5-95percent ACN in water [+ 0.1percent TFA] as the gradient eluent). The fractions containing the desired product were diluted with 4: 1 DCMTPA and washed with saturated NaHC03(aq). The organic extract was dried over anhydrous Na2S04(S), filtered, and concentrated in vacuo to afford the title compound (31.5 mg, 0.0526 mmol, 86.8percent yield). MS (apci) m/z = 539.2 (M+H).
The synthetic route of 5464-12-0 has been constantly updated, and we look forward to future research findings.
