efficient synthesis of 1-(alkoxymethyl)-5-alkyl-6-(arylselenenyl)uracils 8a-e has been accomplished from 6a-b in good yields using a two step procedure. Silylation of 5-alkyl-6-chlorouracils 6a-b using N,O-bis(trimethylsilyl)acetamide followed by regioselective alkylation of the silylated intermediate with ethyl or benzyl chloromethyl ether in dichloromethane afforded the desired 1-(alkoxymethyl)-5-alkyl-6-chlorouracils
