Procedure

A mixture of 4-(bromomethyl)-2-fluoroanisole (45.8 g, 0.21 mol), trihexylamine (1.4 g) and sodium cyanide (20.5 g, 0.42 mol) in water (50 ml) is heated at 60°-65° C. for 18 hours. The mixture is cooled and extracted in its ether, washed with water, saturated sodium chloride solution and dried (CNa2SO4). Evaporation of the solvent gives a solid, (33.2 g): m.p. 42°-46° C.
