Reaction Steps

A mixture of (2,2-difluoro-1,3-benzodioxol-5-yl)-acetonitrile (1.0 eq), 50 wt % aqueous KOH (5.0 eq) 1-bromo-2-chloroethane (1.5 eq), and Oct4NBr (0.02 eq) was heated at 70° C. for 1 hour. The reaction mixture was cooled, then worked up with MTBE and water. The organic phase was washed with water and brine. The solvent was removed to afford (2,2-difluoro-1,3-benzodioxol-5-yl)-cyclopropanecarbonitrile.
