Reaction Steps
500 mg (2.0 mmol) of 5-methyl-5-(3-ethoxy-4-methoxyphenyl)-2-oxazolidinone was first stirred with 60 mg (2.5 mmol) of sodium hydride in 14 ml of dimethylformamide for 30 minutes and, after addition of 0.26 ml (3.0 mmol) of (bromomethyl)cyclopropane for 17 hours at room temperature. The reaction mixture was combined with 50 ml of water and then extracted with ethyl acetate. The ethyl acetate phase was washed with water, dried over sodium sulfate, filtered, and concentrated (766 mg of a yellow oil). Chromatography on silica gel with methylene chloride/ether (1:1) yielded 438 mg of 5-methyl-5-(3-ethoxy-4-methoxyphenyl)-3-cyclopropylmethyl-2-oxazolidinone as an oil.
