Reaktionsschritte

Sodium (0.53 g) was dissolved in ethanol (50 ml) under nitrogen and 4-iodophenol (5.0 g), and 2-chloroethanol (3.93 g), were added successively. The mixture was refluxed for 18 h, treated with saturated aqueous ammonium chloride (50 ml) and evaporated. The aqueous residue was extracted with ER (3×100 ml) and the dried extract was evaporated onto silica (Merck 9385; 50 ml) and purified by [C] eluted with cyclohexane-ER (7:3) followed by cyclohexane-ER (1:1) to give the title compound (3.0 g) m.p. 76°-77°.
