반응 단계
Di-t-butylmethanol is added to a dry flask under argon at 0+ C. Dry tetrahydrofuran is added with a syringe. Sec-Butyl lithium (1.5M in Hexanes) is added quickly in one portion and the contents of the flask are stirred for one hour at room temperature. A 10 mM solution of 18-crown-6-ether in acetonitrile is added with a syringe and the flask cooled to 0° C. A tetrahydrofuran solution of 2-nitropropene is added with vigorous stirring over a 10 minute period. After completion of the reaction as judged by thin layer chromatography, it is quenched with saturated ammonium chloride and extracted with ethyl acetate. The organic layer is dried over MgSO4 and evaporated to yield 2-nitro 1-[di-(t-butyl)methoxy]propane.
