実験手順

A suspension of 3-bromo-2-bromomethylnaphthalene (6.0 g, 0.020 mol), DMSO (150 mL) and sodium cyanide (1.0 g, 0.020 mol) was stirred for 2 hours at room temperature. The resulting solution was added to ice/H2O and extracted well with ethyl acetate. The organic phase was dried over MgSO4, concentrated and dried in vacuo for 16 hours. Treatment of the resulting solid with diethyl ether/hexane afforded 3-bromo-2-naphthalenylacetonitrile (3.6 g), m.p. 116°-117° C.
