实验步骤: The solution of (2-aminopyridin-3-yl)methanol (1.0 g) in THF (dry) (10 mL) was added dropwise to a solution of thionyl chloride (0.736 mL) in THF (dry) (30 mL) at 0° C. The mixture was stirred at room temperature for 30 min and concentrated in vacuo to give 3-(chloromethyl)pyridin-2-amine hydrochloride as a yellow gum. NaH (60%, 147 mg) was added to a mixture of 4-(1-methylpropyl)phenol (503 mg) in DMF (dry) (7 mL) at 0° C. The mixture was stirred at the same temperature for 20 min, then was added with the prepared 3-(chloromethyl)pyridin-2-amine hydrochloride (300 mg) at the same temperature. The mixture was stirred at 0° C. for 20 min, room temperature for 1 hr and 60° C. for 1 hr. Silica-gel was added to the mixture and the volatiles were removed in vacuo. The mixture supported on silica-gel was purified by column chromatography (silica gel, eluted with EtOAc in hexane) to give the title compound (151 mg) as pale yellow crystals. The mixture was stirred at 0° C. for 20 min, room temperature for 1 hr and 60° C. for 1 hr Silica-gel was added to the mixture the volatiles were removed in vacuo was purified by column chromatography (silica gel, eluted with EtOAc in hexane)

实验步骤: To a stirred mixture of 50 ml of water, 50 ml of ether and 10.0 g of 4-sec-butylphenol was added dropwise, 7.5 ml of 61% nitric acid was added dropwise while cooling with ice. After, the temperature of the mixture was raised to room temperature and the reaction was continued for 4 days. The reaction mixture was extracted with 300 ml of ethyl acetate, washed with a brine and dried with anhydrous sodium sulfate. The drying agent was filtered off and the solvent was distilled away. The residue was purified by subjecting to silica-gel column-chromatography [eluent:chloroform] to give 14.71 g of 4-sec-butyl-2-nitrophenol. was added dropwise while cooling with ice The reaction mixture was extracted with 300 ml of ethyl acetate washed with a brine dried with anhydrous sodium sulfate The drying agent was filtered off the solvent was distilled away The residue was purified
