실험 절차

A solution of the compound 1 (33.4 mg, 0.1 mmol) and p-toluenesulfonic acid hydrate (20.4 mg, 0.108 mmol) in a mixture of methylene chloride (1 mL) -toluene (0.1 mL) was concentrated under reduced pressure. Trhe obtained residue was dissolved in methylene chloride (1 mL), to which was added 1-methoxycyclopentene (98.5 mg, 1 mmol), and the mixture was stirred for 2 hours. Triethylamine was added to the reaction mixture, and the mixture was concentrated under reduced pressure. The residue was purified by chromatography on an alumina column (eluate: hexane - ethyl acetate (2:1)) to give the same compound 2 (35 mg, 81 %) as the Example 1.
