실험 절차

0.65 g of 4-acetoxy-3-methoxycinnamoyl chloride was added to a solution of 0.44 g of 1-aminomethyl-4-methyl-2-oxabicyclo[2.2.2]-octan-3-one (Example 30) in 10 ml of pyridine. The resultant solution was stirred at room temperature for 16 hours. After reaction, 30 ml of 2N hydrochloric acid was added to the reaction solution. The resultant solution was extracted five times with 20 ml of ethyl acetate. The organic layer obtained was washed three times with 2N hydrochloric acid, twice with an aqueous sodium hydrogencarbonate solution and once with an aqueous sodium chloride solution, and then was dried over magnesium sulfate. Thereafter, the solvent was removed in vacuo, yielding 0.58 g of N-[1-(4-methyl-2-oxo-3-oxabicyclo[2.2.2]octanyl)methyl]-4-acetoxy-3-methoxycinnamamide (a compound of the present invention) as a pale yellow oil, which had the following physiochemical properties:
