The reaction mixture was diluted with methylene chloride and filtered. The filtrate was washed with 2% aqueous NaOH solution, water, and saturated brine, dried over MgSO4, filtered, and concentrated under reduced pressure. The residue was crystallized from EtOAc/hexanes to give 2.07 g of (3-iodo-naphthalen-2-yloxy)-acetonitrile, MP=105-107° C., MS (M+H)=309.
