Reaction Steps

To a solution of isobutyronitrile (29 mmol) in THF (60 mL) is added LDA (2 M in THF, 35 mmol) at −78° C. After stirring at −78° C. for 2 h, to this solution is added bromomethyl cyclopropane (32 mmol) at −78° C. The mixture is stirred at room temperature for 13 h, and then the reaction is quenched by the addition of aq. NH4Cl. The mixture is extracted with ether, and the combined organic extracts are washed with H2O and brine. The organic layer is dried over MgSO4, filtered, and concentrated in vacuo to give 3-cyclopropyl-2,2-dimethylpropionitrile, which is directly used for the next reaction without further purification.
