Versuchsvorschrift
140 mg of the compound obtained in step 3) was diluted with 3 ml of tetrahydrofuran, and 1.1 ml of a 1.0M tetra-n-butyl ammonium fluoride-containing tetrahydrofuran solution was added thereto. The resulting mixture was incubated at room temperature for three hours. After the reaction terminated, a saturated sodium hydrogen carbonate was added, and the resulting solution was extracted twice with chloroform. The organic layer was dried over anhydrous sodium sulfate, filtered and distilled under a reduced pressure. The resulting residue was purified by column chromatography (ethyl acetate:methylene chloride:methanol=7:7:1) to obtain the title compound (58 mg, 51%).
