実験手順

The compound of Example 287 was reduced in the same manner as in Reference Example 123 and the resulting compound (107 mg) was dissolved in tetrahydrofuran (5.0 mL). A 1 mol/L TBAF-tetrahydrofuran solution (160 μL) was added dropwise and the mixture was stirred for 3 hours at room temperature. Subsequently, water was added and the reaction mixture was extracted with ethyl acetate. The extract was washed sequentially with water and a saturated aqueous solution of sodium chloride and the organic phase was dried over anhydrous sodium sulfate. The solvent was removed by distillation and the residue was purified on a silica gel column chromatography (ethyl acetate only) to obtain the desired product as a colorless oil (47 mg).
