반응 단계
Under a stream of argon, (6-bromopyridine-2-yl)methanol (10 g; 53.2 mmol) was dissolved in methylene chloride (50 mL). Diisopropylethylamine (9.6 g; 74.5 mmol) and chloromethyl methyl ether (5.35 g; 66.5 mmol) were added to the reaction mixture in an ice bath, and further, the reaction mixture was stirred at room temperature for 17 hours. The reaction solution was poured into ice water and extracted with chloroform. The organic layer was washed with water, dried over sodium sulfate, and then evaporated under reduced pressure. The resulting residue was separated and purified by silica gel column chromatography (SiO2, 200 g) (toluene/ethyl acetate=10/1) to give 12.15 g (yield: 98%) of the title compound (11).
