Reaction Steps
To a solution of 1-methyl-1-[4-(N-acetyl-phenylsulfonylamino)-3-methoxyphenyl]ethanol (2.50 g; prepared in Reference Example 39.) in methylene chloride (10 ml), trifluoroacetic acid (10 ml) and triethylsilane (3.3 ml) were added at 0° C. The mixture was stirred for 1 hour at room temperature. The reaction mixture was added to saturated sodium hydrogencarbonate carefully The mixture was extracted with ethyl acetate. The organic layer was washed, dried over and concentrated. The residue was purified on silica gel column chromatography (hexane:AcOEt=3:1) to give the title compound (2.33 g) having the following physical data.
