Procedure

A solution of sodium ethoxide in ethanol (20 mls) [prepared from 0.16 g (0.006 g-atom) of sodium metal] and the thioacetate produced in Example 63 (2.1 g, 0.0055 mol) was stirred for one hour at room temperature under nitrogen. Ethanol was removed in vacuo on the rotary evaporator and the residue dissolved in ethyl acetate. This organic phase was washed with 0.5N sodium bisulfate solution and dried over sodium sulfate. The drying agent was filtered and the filtrate concentrated on the rotary evaporator to give 1.97 g (95%) of the title compound as an oil.
