실험 절차

1-(2-Deoxy-β-D-ribofuranosyl)-4-iodo-2-nitropyrrole (Compound 1) (354 mg, 1.0 mmol), Pd(PPh3)4 (58 mg, 0.05 mmol), CuI (30 mg, 0.16 mmol) and triethylamine (209 μl, 1.5 mmol) were dissolved in DMF (3.5 ml), followed by addition of a 1 M DMF solution of N-(2-propynyl)-dichloroacetamide (1.5 ml, 1.5 mmol). After stirring at room temperature for 12 hours, the reaction mixture was partitioned between ethyl acetate and water, and the organic layer was washed three times with water. After drying over anhydrous sodium sulfate, the organic layer was concentrated and purified on a silica gel column (CH2Cl2:MeOH, 20:1, v/v) and by HPLC (34%-35% CH3CN, 12 minutes) to give Compound 3 (317 mg, 81%).
