0.84 ml of a 1M sodium hydroxide solution was added to a solution of 256 mg of 5'-amino-5-bromo-2',5'-dideoxycytidine in 3.3 ml of water. A solution of (2-bromophenyl)acetyl chloride (prepared from 185 mg of the acid) in 5 ml of dichloromethane was added, the mixture was shaken vigorously for 10 minutes and then filtered. The solid was recrystallized from 30 ml of ethanol to give 44 mg of 5-bromo-5'-[2-(2-bromophenyl)acetamido]-2',5'-dideoxycytidine in the form of a white solid of melting point 164°-167° C.
