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 4-{[(2-hydroxyethyl)oxy]methyl}benzonitrile (95 mg, 0.536 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 (60 mg, 47%). 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

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). 4-(Bromomethyl)benzonitrile (290 mg, 1.5 mmol) was added to the reaction, and the residual 4-(bromomethyl)benzonitrile 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: 10% EtOAc/hexanes (fractions 1,2), 30% EtOAc/hexanes (fractions 3,4), 50% EtOAc/hexanes (fractions 5-7), and 75% EtOAc/hexanes (fraction 8) to give the title compound (95 mg, 36%).

実験手順: 4-[(2-Hydroxyethoxy)methyl]benzonitrile (5.5 g, 30.5 mmol; see step (i) above) was dissolved in DCM (61 mL) and cooled to −10° C. Triethylamine (5 mL, 36.5 mmol) and methanesulfonyl chloride (3.84 g, 33.5 mmol) were added and the resulting mixture was stirred at below −5° C. for 1.5 h and then at RT overnight. Dichloromethane (200 mL) was added and the mixture was washed with water (2×100 mL) and then dried over Na2SO4. Evaporation of solvents gave 7.3 g (94%) of the title compound, which was used without further purification. at RT overnight the mixture was washed with water (2×100 mL) dried over Na2SO4 Evaporation of solvents
