반응 단계

1.25 of 1M sodium hydroxide solution were added to 0.255 g of 5'-amino-2',5'-dideoxy-5-ethyluridine in 5 ml of water and then 0.2 g of 2-phenylbutyryl chloride was added to the mixture. The resulting mixture was shaken for 10 minutes, whereby a white solid was deposited. This solid was collected by filtration, washed three times with 5 ml of water each time, dried at 50° C. in vacuo over phosphorus pentoxide and recrystallized from ethanol to give 0.28 g of 2',5'-dideoxy-5-ethyl-5'-(2-phenylbutyramido)uridine of melting point 235°-236° C.
