Versuchsvorschrift

Under the argon atmosphere, dimethyl-(3-phenoxy-2-oxopropyl)-phosphonate (826 mg, 3.20 mmol) and potassium phosphate (679 mg, 3.20 mmol) were added to a THF solution (16 mL) of the compound (634 mg, 1.60 mmol) produced in Example 13, and the mixture was stirred at room temperature for one day. The reaction solution was added to an aqueous saturated ammonium chloride solution, and the aqueous layer was extracted with ethyl acetate two times. The collected organic layers were washed with a saturated saline, and dried with anhydrous sodium sulfate. The solution was concentrated under reduced pressure, and purified with a column apparatus (Hiflash-SI, Size L, hexane→ethyl acetate:hexane=4:6) manufactured by Yamazen Corporation to obtain a titled compound (426 mg) having the following physical property values.
