実験手順

To a mixture of 10 ml of THF and 0.20 g of 3-methoxy-4-(2-propynyloxy)benzoyl chloride were added dropwise 0.22 g of cyclohexylmethylamine and 0.20 g of triethylamine in order under ice cooling The mixture obtained was stirred at room temperature for 4 hours. Then, the reaction mixture was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 0.22 g of N-cyclohexylmethyl-4-(2-propynyloxy)-3-methoxybenzamide (hereinafter, described as the compound 17 of the present invention) represented by the formula:
