2-Bromophenylacetyl chloride → 4-N-benzoyl-5'-[2-(2-bromophenyl)acetamido]-2',5'-dideoxy-5-ethylcytidine

Participants

Reaction Steps

A solution of 210 mg of (2-bromophenyl)acetyl chloride in 3 ml of diethyl ether was added to a solution of 324 mg of 5'-amino-4-N-benzoyl-2',5'-dideoxy-5-ethylcytidine in 4.9 ml of 0.18M sodium hydroxide solution and the mixture was shaken vigorously for 10 minutes. The solid was collected by filtration, washed with 2 ml of water and 1 ml of diethyl ether and recrystallized from 15 ml of ethanol to give 100 mg of 4-N-benzoyl-5'-[2-(2-bromophenyl)acetamido]-2',5'-dideoxy-5-ethylcytidine in the form of a white solid which was processed further without purification.
