反応手順

Nicotinyl chloride hydrochloride (8.9 gm.) was added to a stirred solution of 3-ethyl-3-hydroxymethyloxetane (5.8 gm.) and dry pyridine (20 ml.) in dry dichloromethane (150 ml.) at 0°. The mixture was stirred at room temperature for 4 days and poured into aqueous sodium carbonate solution. The aqueous mixture was extracted with dichloromethane. The extracts were washed with water and dried over anhydrous magnesium sulphate. The solvent was removed in vacuo. The residue was purified by chromatography on silica eluting with 5% triethylamine in dichloromethane. (3-Ethyloxetan-3-yl)methyl 3-pyridinecarboxylate was obtained as a pale yellow oil (7.0 gm.).
