実験手順

The compound (1.01 g) obtained in Example 29-3, WSCI hydrochloride (973 mg), and HOBt (894 mg) were dissolved in chloroform (30 ml), and the whole was stirred for 2 hours. Then, the compound (445 mg) obtained in Example 29-1 was added thereto and the whole was stirred at room temperature for 3 hours. After completion of the reaction, the solvent was distilled off under reduced pressure. Then, the residue was dissolved in chloroform and washed with a saturated ammonium chloride aqueous solution, a saturated aqueous sodium hydrogen carbonate solution, and a saturated saline solution. After that, the resultant was dried with anhydrous sodium sulfate. After filtration, the solvent was distilled off under reduced pressure. The residue was purified through silica gel column chromatography (chloroform/ethyl acetate), thereby obtaining the subject compound (613 mg) as an orange solid.
