Alkylation of malonamic esters provides a direct approach to derivatives of suberoylanilide hydroxamic acid (SAHA) that are branched at the amide carbon atom, a location pivotal for enhancing biological and therapeutic activity. Alkylations use NaH in THF followed by addition of the ester of 6-bromohexanoic acid; no protection of the amidic NH group is necessary. By this means, carboxylic acid, ester
