Procedure

0.32 g of 5'-amino-5-(2-chloroethyl)-2',5'-dideoxyuridine hydrochloride were dissolved in a mixture of 5 ml of water and 2.5 ml of 1M sodium hydroxide solution. The mixture was shaken vigorously for 25 minutes with a benzene solution of (2,6-dichlorophenyl)acetyl chloride (prepared from 0.22 g of the acid by treatment with oxalyl chloride). The resulting solid was removed by filtration and washed with water and then with diethyl ether to give 0.29 g of crude product of melting point 248°-249° C. (decomposition). 0.1 g of this solid was stirred successively for 1 hour each time with 1 ml of water, 2 ml of ethanol and 2 ml of methanol to give 0.03 g of 5-(2-chloroethyl)-5'-[2-(2,6-dichlorophenyl)-acetamido]-2',5'-dideoxyuridine of melting point 253°-254° C. (decomposition).
