Procedure

A solution of (2,6-dichlorophenyl)acetyl chloride (prepared from 146 mg of the acid) in 1 ml of diethyl ether was added to a solution of 170 mg of 5'-amino-2',3',5'-trideoxy-5-ethyluridine in 2.72 ml of 0.26M sodium hydroxide solution and the mixture was shaken for 10 minutes. The mixture was filtered and the solid was recrystallized from 20 ml of ethanol to give 150 mg of 2',3',5'-trideoxy-5'-[2-(2,6-dichlorophenyl)acetamido]-5-ethyluridine in the form of a white solid of melting point 237°-238° C.
