Procedure

1'-bromo-3',5',5-tris(methoxybenzyl)thymidine in ethanol is added to a stirred solution of sodium ethoxide in ethanol at -10 ° C. The resulting reaction mixture is stirred at room temperature fro 1 h, neutralized with dilute hydrochloric acid. Ethanol is evaporated and the remaining mixture extracted with ethyl acetate. The crude is purified by chromatography to give a mixture of α and β diasteriomers.
