Procedure

A mixture of β-naphthol (1 gm, 0.006 mole), anhydrous K2CO3 (10 gm, in excess) and 1-bromo-2-chloroethane (0.6 ml, 0.006 mole) was refluxed in dry acetone (50 ml) for 6 hours. Reaction mixture was filtered and filtrate was concentrated to get oily compound, which was crystallized with benzene-hexane to give the colorless crystals of pure desired compound. m.p. 94° C., (yield 1.36 gm, 96%).
