Procedure
1.0 g (0.021 mol) of 50% sodium hydride, 25 ml of dimethylformamide, 3.2 g (0.019 mol) of ethyl 4-hydroxybenzoate and 6.1 g (0.019 mol) of (S)-2-tetrahydropyranyloxypropoxy p-toluenesulfonate were reacted at 60° C. for 8 h. Then the same procedure as in Referential Example 1 was repeated to obtain 5.0 g of the crude product.
