Reaction Steps

50 mg of 7-chloro-4,5-dihydro-1,4-benzoxazepin-5-one was dissolved in dimethylformamide (1 ml), then 12 mg (1.2 equivalents) of 60% sodium hydride was added under ice cooling. This was agitated for 30 minutes, then 54 mg (1.5 equivalents) of 1-bromo-2-chloroethane was added and the result was agitated at room temperature for 10 hours. Ice water was added to the reaction solution, and extraction was performed by ethyl acetate. This ethyl acetate extract was washed by saline and was dried with anhydrous magnesium sulfate. The solvent was distilled off and the resultant crude product was refined with silica gel column chromatography (hexane: ethyl acetate=4:1) to obtain the above-referenced compound in an amount of 28 mg (yield of 42%).
