Versuchsvorschrift

A solution of 14.4 g. of 2-naphthol, 12.1 g. of 2-bromoethanol and 5.9 g. of sodium methoxide in 100 ml. of ethanol is allowed to stand two days at room temperature. The solvent is removed under vacuum and the residue extracted with ether. The ether extract is washed with water, dried (magnesium sulfate) and the solvent removed under vacuum to give crystals, m.p. 65°-70° C.
