実験手順
To a solution of 2-azepan-1-ylethanol (5.0 g) in N,N-dimethylformamide (100 ml) was added 60% sodium hydride (1.5 g) under a nitrogen atmosphere, the solution was stirred for 1 hour at room temperature, 2,5-dibromopyridine (7.5 g) was then added thereto followed by stirring for 4.5 hours at room temperature. Water was added thereto followed by stirring, the solution was extracted with ethyl acetate, then sequentially washed with water and brine, dried over anhydrous magnesium sulfate, and then the solvent was evaporated in vacuo. The residue was purified by NH silica gel column chromatography (hexane-ethyl acetate system) to provide the title compound (9.1 g).
