were alkylated with ethoxymethyl chloride to give the alkylated imidazoles 5a-d which were considered analogues of Emivirine with deletion of carbonyl group at the 4-position. Alkylation of 7a-d afforded the corresponding S-alkylated derivatives 8a-p which in a similar way were considered analogues of S-DABO. However all the imidazole derivatives were devoid of activity against HIV.
