L, 2.52 mmol) was added dropwise over 5 minutes.
For a minute. The reaction mixture was diluted with methylene chloride and washed with saturated aqueous sodium hydrogen carbonate. After the organic layer was dried over anhydrous magnesium sulfate, the solvent was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, and hexane /
1.19 g (98%) of yellow oily compound 5 was obtained from the ethyl acetate (1/1) elution part.
