実験手順
Following the same method as described in Example 2, 7.36 g (15 mmol) of tetraethyl 2-[3-methylthio-4-hydroxy-1-naphthyl]ethane-1,1-diphosphonate was treated with trimethylsilyl bromide, and then hydrolysis was effected to obtain 4.03 g of the title compound as pale yellow crystals. The yield was 71%.
