Procedure

2.69 g of 2-hydroxy-3-phenyl-3-(2-methoxy-phenoxy)-propionitrile dissolved in 25 ml of anhydrous DMF and 7.1 g of methyl iodide were stirred at 0° C. Addition was made, in portions, of 2.18 g of 55% NaH. After the addition, the whole was stirred at 0°-5° C. for 1 and a half hours. Under an atmosphere of nitrogen the whole was then decomposed cautiously with water, diluted with plentiful water, extracted with ethyl acetate and washed with water. The organic phase was dried over Na2SO4 and evaporated to dryness, in this way obtaining 1.95 g of 2-methoxy-3-phenyl-3-(2-methoxy-phenoxy)-propionitrile as an oil. Yield=69%.
