4,4-二甲基-3-氧亚基己腈

反应条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A suspension of sodium hydride (60% dispersion in mineral oil, 3.18 g, 79.4 mmol) in tetrahydrofuran (60 mL) was heated at 60° C. for 1 hour. The reaction mixture was then cooled to room temperature, acetonitrile (4.2 mL, 79.4 mmol) and 2,2-dimethyl-butyric acid ethyl ester [(7.95 g, 61 mmol), J. Am. Chem. Soc., 1942, 64, 2964] in tetrahydrofuran (100 mL) were added and the mixture was stirred for 4 hours at 25° C. The mixture was then diluted with 1M hydrochloric acid (100 mL) and the aqueous layer was separated and extracted with ethyl acetate. The organic solution was then dried over magnesium sulfate, concentrated in vacuo and the residue was triturated with heptane to afford the title compound as a pale brown solid in 27% yield, 2.3 g. The reaction mixture was then cooled to room temperature the aqueous layer was separated extracted with ethyl acetate The organic solution was then dried over magnesium sulfate concentrated in vacuo the residue was triturated with heptane
