Procedure

Compound f, 2.0 g, obtained in Reference Example 6 was dissolved in 100 ml of methylene chloride and 0.7 ml of phenyl isocyanate was added to the solution. The mixture was stirred at room temperature for 2 hours. The solvent was distilled off under reduced pressure. The residue was extracted with 200 ml of ethyl acetate. The extract was washed with saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure. The resulting residue was subjected to silica gel column chromatography (eluting solvent; hexane:ethyl acetate=2:1) to give 2.2 g of the desired compound.
