Versuchsvorschrift
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.
