실험 절차
0.05 g of 5'-[2-(2-bromophenyl)-N-methylacetamido]-2',5'-dideoxy-5-ethyluridine was dissolved in 2 ml of dry pyridine and the solution was treated with 0.12 ml of acetic anhydride. The mixture was stirred at room temperature for 5 hours and then evaporated. The residue was re-evaporated with toluene to give a solid which was triturated with diethyl ether and then removed by filtration. There was obtained 0.03 g of 3'-O-acetyl-5'-[2-(2-bromophenyl)-N-methylacet-amido]-2',5'-dideoxy-5-ethyluridine of melting point about 170° C.
