Versuchsvorschrift

Using the method described in Example 1, the crude solids were prepared using 5.5 g (0.24 gram atoms) sodium metal, 34.6 g (0.24 mole) 2-naphthol, and 27.2 g (0.100 mole) 1,8-dibromooctane. Recrystallization from ethyl acetate gave 30.0 g, mp 128° C., and 0.8 g, mp 125°-126° C., of pure 1,8-bix (2-naphthoxy) octane. The NMR spectrum was consistent with the structure and showed the absence of impurities.
