192130-34-0, tert-Butyl 4-(2-aminoethyl)piperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A resealable tube was charged with 4-chloro-2-(3-fluoro-4-(2-(piperidin-1-yl)ethoxy)phenyl)-3-phenylfuro[2,3-b]pyridine 6e (0.096 g, 0.213 mmol), 4-N-(tert-butoxycarbonyl)-1-aminoethylpiperazine (0.098 g, 0.426 mmol), potassium carbonate (0.589 g, 4.26 mmol), and toluene (3 mL). The Pd/BINAP solution was added along with 1.5 mL of toluene, and the system was flushed with argon. The tube was sealed and the mixture stirred at 130° C. for 20 h. The reaction mixture was partitioned between ethyl acetate and saturated aqueous sodium bicarbonate solution. The aqueous phase was separated and extracted with ethyl acetate. The combined organic phases were washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, filtered and concentrated to afford an orange brown oil. This oil was purified via preparative thin layer chromatography (eluting with 95:5:0.5, dichloromethane/methanol/ammonium hydroxide) to afford tert-butyl 4-(2-(2-(3-fluoro-4-(2-(piperidin-1-yl)ethoxy)phenyl)-3-phenylfuro[2,3-b]pyridin-4-ylamino)ethyl)piperazine-1-carboxylate (not shown) as a yellow oil. MS (MH+) 644.4; Calculated 643 for C37H46FN5O4., 192130-34-0
The synthetic route of 192130-34-0 has been constantly updated, and we look forward to future research findings.
