title: Solid-phase synthesis of an alkylaminobenzanilide library.
abstract: The synthesis of a library of 2- and 3-substituted benzanilides has been achieved on solid phase. Attachment of anilines to formyldimethoxyphenyl (FDMP) resin via reductive amination was optimized to allow a wide range of anilines to be used. Acylation of this resin-bound aniline was accomplished with 2- or 3-nitrobenzoyl chloride to yield nitrobenzanilides. Following reduction of the nitro group, the resulting amine was alkylated using aromatic and heteroaromatic aldehydes in the presence of NaBH(OAc)(3) under controlled conditions. Finally, the products were cleaved from the resin using trifluoroacetic acid to produce a 10 800-member library.
