Methyl iodide → HCID 86648183, compound

Participants

Reaction Steps

To a cooled (−78° C.) solution of tert-butyl(4-cyanocyclohexyl)methylcarbamate (500 mg) in tetrahydrofuran (10 mL) was added lithium diisopropylamide (2.0 mL, 2M in heptane). The mixture was stirred at −78° C. for 30 minutes before the addition of CH3I (1 mL). The mixture was then stirred and the temperature was allowed to warm to room temperature. The reaction was quenched with aqueous NH4Cl and the mixture was extracted with ethyl acetate (300 mL) and washed with water, brine and dried over Na2SO4. Filtration and evaporation of the solvent and silica gel chromatography (40% ethyl acetate in hexane) of the crude material gave the title compound.
