Synthesis of 1-(aryloxyalkyl)-5-(arylamino)uracils

Article abstract of DOI:10.1007/BF02290947

In an attempt to obtain new non-nucleoside inhibitors of the reverse transcriptase HIV-1, we have carried out the synthesis of 1-(benzyloxymethyl)- and 1-[2-(4-R-phenoxy)ethyl]-5-(arylamino)uracils. Indirect alkylation of trimethylsilyl derivatives of 5-(arylamino)uracils with benzyl chloromethyl ether by the Gilbert-Jones method did not affect the exocyclic amino group and gave the corresponding 1-(benzyloxymethyl) derivatives in 58-74% yield. Alkylation of 5-(arylamino)uracils with 1-bromo-2-(4-R-phenoxy)ethane in anhydrous DMF in the presence of potassium carbonate gave a mixture of N¹-mono- and N¹,N¹-disubstituted products with an overall yield of 46-55%. 1998 Plenum Publishing Corporation.
