Versuchsvorschrift
Compound 44 (100 mg) and (2,2,2-trichloroethyl) phosphorochloridate (256 mg) were dissolved in pyridine (2 mL), and the resultant solution was stirred for two hours. After completion of reaction, the resultant reaction mixture was concentrated to dryness under reduced pressure, followed by purification by means of silica gel chromatography employing a chloroform/methanol system. The thus-purified product was dissolved in a pyridine-acetic acid (4:1) solvent mixture, and zinc powder (140 mg) was added to the resultant solution, followed by stirring for two hours. After completion of reaction, the resultant reaction mixture was concentrated to dryness under reduced pressure, followed by purification by means of silica gel chromatography employing a chloroform/methanol system, to thereby produce the target product (83 mg, yield: 70%).
