참여 물질

반응 단계

To a mixture of 10 ml of THF and 0.40 g of 3-fluoro-4-(2-propynyloxy)benzoyl chloride were added 0.45 g of cyclohexylmethylamine and 0.50 g of triethylamine in order at room temperature. The mixture obtained was stirred at room temperature for 1 hour. Then, ethyl acetate was added to the reaction mixture and the mixture was filtered through Celite. The filtrate was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 0.35 g of N-cyclohexylmethyl-3-fluoro-4-(2-propynyloxy)benzamide (hereinafter, described as the compound 22 of the present invention) represented by the formula:
