実験手順

5-(tert-Butyldiphenylsilanyloxy)-3-(4-trifluoromethylphenyl)pentanoic acid amide (640 mg) was dissolved in methylene chloride (13 mL), and 1,8-diazabicyclo[5,4,0]undec-7-ene (862 μL) and methyl dichlorophosphate (301 μL) were added at 0° C. After stirring at room temperature for 1.5 hours, the reaction was terminated with a saturated sodium bicarbonate aqueous solution. The organic layer was washed with brine and then dried over magnesium sulfate. Concentration under reduced pressure gave an oil. The oil was allowed to pass through a silica gel pad (mobile phase:ethyl acetate:heptane=1:2) to obtain the title compound (600 mg).
