769944-78-7,769944-78-7, 1-N-Boc-4-(4-Bromophenyl)piperidine is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of tert-butyl 4- (4-bromophenyl) piperidine-1-carboxylate (510 mg, 1.499 mmol) , 4, 4, 4′, 4′, 5, 5, 5′, 5′-octamethyl-2, 2′-bi (1, 3, 2-dioxaborolane) (761 mg, 3 mmol) and KOAc (441 mg, 4.5 mmol) in DME (20 ml) was degassed with N2 and PdCl2 (dppf) -CH2Cl2 (122 mg, 0.15 mmol) was added. The resulting mixture was degassed with N2 again and was heated to 80 overnight. After cooling to rt, the mixture was added with 10mL of NH4Cl (aq) , and extracted with EtOAc (20mL ¡Á 2) . The combined organic phase was washed with brine (20mL) , dried over Na2SO4 (anhydrous) , filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (EA/Hexane 0: 100-1: 5) to give the title compound (500 mg , 86) . 1H NMR (400 MHz, CDCl3) delta ppm 1.27 (s, 9H) , 1.34 (s, 12H) , 1.57 -1.72 (m, 2H) , 1.82 (br d, J13.05 Hz, 2H) , 2.66 (br s, 1 H) , 2.80 (br t, J12.05 Hz, 2H) , 4.25 (br d, J12.80 Hz, 2H) , 7.11 -7.42 (m, 2H) , 7.77 (d, J8.03 Hz, 2H) . LC-MS: [M+H-100] + 288.2.
As the paragraph descriping shows that 769944-78-7 is playing an increasingly important role.
