Procedure

The compound obtained in Example 13 (3.7 g, 10.2 mmol) was dissolved in tetrahydrofuran (100 ml). Imidazole (2.1 g, 30.6 mmol), triphenylphosphine (4.0 g, 15.3 mmol) and iodine (3.9 g, 15.3 mmol) were added, and stirred for 8 h at 0° C.˜room temperature. After completion of the reaction, ethyl acetate (100 ml) was added, and the reaction mixture was washed with water (100 ml×2). The organic layer was concentrated and the residue was purified by column chromatography to give the title compound (2.0 g, 4.07 mmol, Yield 40%).
