실험 절차

A mixture of 783 mg of thiobenzamide and 1.0 g methyl 2-(9-chloro-8-oxononyloxy)-2-methylpropionate were stirred for 2 hours at 120° C. The reaction solution was cooled and dissolved in ethyl acetate, washed by adding sodium hydrogencarbonate, washed with water, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by silica gel column chromatography (Wakogel® C-200, n-hexane:ethyl acetate=9:1) to provide 963 mg of the objective compound as pale yellow oil.
