Methyl iodide → HCID 70109935, compound

Participants

Reaction Steps

To a solution of ethyl cyanoacetate (2.07 g, 18.3 mmol) in DMF (40 ml) was added under ice-cooling sodium hydride (0.77 g, 19.2 mmol). After stirring for one hour, cyclohexyl isothiocyanate (2.59 g, 18.3 mmol) was added dropwise. After stirring under ice-cooling for 1.5 hours, methyl iodide (2.60 g, 18.3 mmol) was added dropwise. After stirring at room temperature for 15 hours, water (400 ml) was added to the reaction mixture, which was then extracted with ethyl acetate (100 ml×2). The organic layer was washed with a saturated aqueous solution of sodium chloride, dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound as a yellow oily substance (4.76 g) from the fraction from hexane-ethyl acetate (4/1). Yield=97%.
