Reaction Steps

2.5 g (11.0 mmol) of 3-(4-hydroxytetrahydrofuran-3-yloxy)-4-methoxybenzonitrile (A 15) in 12 ml of dimethylformamide are added dropwise under a nitrogen atmosphere to a solution of 350 mg (12.0 mmol) of sodium hydride in 12 ml of dimethylformamide and the mixture is heated at 40° C. for 1 h. 1.6 ml (13.0 mmol) of benzyl chloride, dissolved in 6 ml of dimethylformamide, are then added dropwise at RT. The mixture is stirred at RT for 4 h. concentrated, treated with 50 ml of water and acidified with 2 N hydrochloric acid. After extraction with 3×40 ml of ethyl acetate, the combined organic phases are washed with saturated sodium chloride solution, dried over magnesium sulfate and concentrated. For further purification, the product is chromatographed on silica gel [toluene/ethyl acetate=4:1]. The product-containing fractions are concentrated and the residue is crystallized from isopropanol. 3.05 g of the title compound of m.p. 72-75° C. are obtained.
