反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of N-bromosuccinimide (272 mg, 1.53 mmol) in DCM (2.5 mL) was added to resin-bound triphenylphosphine (510 mg, 1.53 mEquiv, Fluka) in DCM (2.5 mL), and the reaction was stirred at rt for 10 min. A solution of 2-{[(4-bromophenyl)methyl]oxy}ethanol (139 mg, 0.601 mmol) in DCM (1.5 mL) was added to the reaction, and the residual alcohol was transferred with additional DCM (1.5 mL). The reaction vial was capped, wrapped in aluminum foil, and stirred at rt for 20 h. The reaction was filtered through a SPE cartridge (5 g silica) eluting with the following 10 mL fractions: DCM (fraction 1), 30% EtOAc/hexanes (fraction 2), and 50% EtOAc/hexanes (fraction 3) to give the title compound (87 mg, 49%). The product was characterized by 1H NMR (400 MHz) in CDCl3. The reaction vial was capped stirred at rt for 20 h The reaction was filtered through a SPE cartridge (5 g silica) eluting with the following 10 mL fractions

反応条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Ethylene glycol (0.084 mL, 1.5 mmol) was added to NaH (38 mg, 1.52 mmol, 95% in oil) in THF (3 mL). 1-Bromo-4-(bromomethyl)benzene (370 mg, 1.5 mmol) was added to the reaction, and the residual 1-bromo-4-(bromomethyl)benzene was transferred to the reaction tube with additional THF (1 mL). (Bu)4NI (55 mg, 0.15 mmol) was then added, and the reaction was heated at 60° C. for 18 h and then rt for 4 h. H2O (2 mL) and EtOAc (2 mL) were added, and the layers were separated via pipette. The aqueous layer was extracted with EtOAc (1×1 mL), and the combined organic layers were concentrated. The crude product was purified on a SPE cartridge (5 g silica) eluting with the following 10 mL fractions: 30% EtOAc/hexanes (fractions 1,2), 50% EtOAc/hexanes (fraction 3), and 75% EtOAc/hexanes (fraction 4) to give the title compound (139 mg, 40%). The product was characterized by 1H NMR (400 MHz) in CDCl3. the layers were separated via pipette The aqueous layer was extracted with EtOAc (1×1 mL) the combined organic layers were concentrated The crude product was purified on a SPE cartridge (5 g silica) eluting with the following 10 mL fractions
