反応手順

A solution of 310 mg (1 mmol) of 1-triphenylmethylimidazole (K H. Buchel et al.; Drugs Made in Germany, 1972, 15, 77) in 12 ml of dry THF is cooled to 0° under nitrogen and treated with 0.647 ml (1.1 mmol) of 1.7M solution of n-BuLi in hexane. The solution is stirred at room temperature for 1 hour, then recooled to 0° and treated with 405 mg (1.5 mmol) of 1-iodo-3-(tetrahydropyran-2-yloxy)propane dissolved in 2 ml of dry THF. The reaction mixture is allowed to warm to room temperature overnight, then poured into water and extracted with ethyl acetate. The organic extract is rinsed with brine and dried (MgSO4). Removal of solvents in vacuo affords the title A compound.
