At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-(4-Iodophenyl)ethanol, and friends who are interested can also refer to it.
Reference of 52914-23-5, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 52914-23-5 name is 2-(4-Iodophenyl)ethanol, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
3-[4-[2-(Benzyloxy)ethyl]phenyl]-5-[[1-(tert-butoxycarbonyl)-2(S)-azetidinyl]methoxy]pyridine Into a 50-mL 3-necked round-bottom flask under N2 was placed a solution of 2-(4-iodophenyl)ethanol (470 mg, 1.90 mmol) in tetrahydrofuran (10 mL). Sodium hydride (91 mg, 3.8 mmol, 1.2 equiv.) was added at 0 C. The mixture was warmed to room temperature and stirred at room temperature for 2 h. Benzyl bromide (272 muL, 3.9 mmol, 1.2 equiv.) and tetra-n-butylammonium bromide (61 mg, 0.19 mmol, 0.10 equiv.) were added at room temperature. The resulting solution was stirred for 20 h at room temperature. The reaction was then quenched by the addition of 10 mL of aqueous NH4Cl. The solution was extracted with 3*60 mL of EtOAc, and the organic layers were combined and washed with 50 mL of brine. After evaporation, the residue was applied onto a silica gel column, and the product was eluted with EtOAc/petroleum ether 1:20 to furnish 600 mg (94%) of 1-[2-(benzyloxy)ethyl]-4-iodobenzene as a white solid. A solution/suspension of 3-[[1-(tert-butoxycarbonyl)-2(S)-azetidinyl]methoxy]-5-(trimethylstannyl)pyridine (427 mg, 1.00 mmol), 1-[2-(benzyloxy)ethyl]-4-iodobenzene (338 mg, 1.00 mmol), CsF (304 mg, 2.00 mmol), Pd(PPh3)4 (58 mg, 0.05 mmol) and CuI (19 mg, 0.10 mmol) in anhydrous DMF (5 mL) was stirred at 50 C. for 5 h under N2. The reaction mixture was cooled and concentrated under vacuum. The residue was applied onto a silica gel column, and the product was eluted with EtOAc/petroleum ether/Et3N 3:6:0.5 as the eluent to give the title compound (280 mg, 59%) as light-yellow oil. 1H NMR (CDCl3, 300 MHz) delta 8.48 (s, 1H), 8.33 (d, J=2.1 Hz, 1H), 7.55 (d, J=8.1 Hz, 2H), 7.48 (s, 1H), 7.37-7.29 (m, 7H), 4.57 (s, 3H), 4.42 (s, 1H), 4.24 (dd, J=7.2, 3.0 Hz, 1H), 3.93 (t, J=7.2 Hz, 2H), 3.75 (t, J=7.2 Hz, 2H), 3.00 (t, J=7.2 Hz, 2H), 2.43-2.30 (m, 2H), 1.42 (s, 9H). LC-MS (ESI) m/z 475 (M+H+).
