実験手順

The triethylammonium salt of compound 53 (50.0 mg, 0.09 mmol) was dissolved in HMPA (2 mL) and 1,1′-carbonyldiimidazole (106 mg, 0.66 mmol) was added at room temperature and stirred for 2 h. Methanol (35 μL) was added and stirring was continued for 45 min. The tri-n-butylammonium salt of imidodiphosphate (427 mg, 0.46 mmol) dissolved in HMPA (2 mL) was added with syringe to the solution of activated AZT monophosphate, and the combined solution was stirred at room temperature for 4 h. The reaction mixture was cooled in ice-bath and water (5 mL) was added. Purification by HPLC gave 30.6 mg of the titled compound 57.
