Dimethylformamide → 2-(Cyclohexylmethoxy)pyrimidine-4-carbaldehyde

Participants

Reaction Steps

Knochel-Hauser reagent (2,2,6,6-tetramethylpiperidinylmagnesium chloride lithium chloride complex) is added to a mixture of 2-(cyclohexylmethoxy)pyrimidine in THF at −78° C., stirred for 15 min, then DMF is added. The reaction mixture is stirred at −30° C., quenched by aqueous NH4Cl, extracted with ethyl acetate. Combined organic layers are dried over anhydrous Na2SO4 and concentrated under reduced pressure to give 2-(cyclohexylmethoxy)-pyrimidine-4-carbaldehyde.
