0.07 g of sodium hydride (60% oil suspension) was suspended in 3 ml of tetrahydrofuran. The 0.5 ml of tetrahydrofuran solution of 0.12 g of 2-butyn-1-ol was added dropwise at room temperature therein, and the mixture was stirred for 10 minutes. Into the mixture was added dropwise 0.5 ml of tetrahydrofuran solution of 0.34 g of 1-(6-chloro-5-fluoropyrimidin-4-yl)-2,5-dimethyl-hexahydro-1H-azepine at room temperature, and stirred for 8 hours at 60° C. After the reaction mixture was cooled to near room temperature, a saturated ammonium chloride aqueous solution was added therein, and the mixture was extracted with tert-butyl methyl ether three times. The organic layers were washed with a saturated sodium chloride aqueous solution, dried over anhydrous magnesium sulfate and concentrated. The residue was subjected to silica gel column chromatography to obtain 0.35 g of 1-(6-(2-butynyloxy)-5-fluoropyrimidin-4-yl)-2,5-dimethyl-hexahydro-1H-azepine (hereinafter, referred to as Compound (35)).
