To a mixture of 5 ml of ethyl acetate and 0.30 g of 3-fluoro-4-(2-propynyloxy)benzoyl chloride were added 0.22 g of (1S)-1-(cyclohexyl)ethylamine and 0.20 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 washed with hexane to obtain 0.37 g of N-((1S)-1-cyclohexylethyl)-3-fluoro-4-(2-propynyloxy)benzamide (hereinafter, described as the compound 37 of the present invention) represented by the formula:
