Potassium Carbonate → (S)-4-(Oxiran-2-ylmethoxy)benzonitrile

Participants

Reaction Steps

Potassium carbonate (414 g) and (R)-(−)-epiclorohydrin (800 mL) were added to a stirred solution of p-cyanophenol (238 g) in 2.0 L MeCN and the reaction mixture was refluxed under an inert atmosphere for 2 h. The hot solution was filtered and the filtrate concentrated, giving a clear oil which was crystallised from di-iso-propyl ether giving the product in 90% yield.
