title: A new synthesis of Rink's polymer, 4-(2',4'-dimethoxyphenylhydroxymethyl)phenoxymethylpolystyrene .
abstract: For solid-phase peptide synthesis, 2,4-dimethoxy-4'-hydroxbenzhydrol linker was prepared via lithium borohydride reduction of 2,4-dimethoxy-4'-hydroxybenozophenone. The potassium salt of the linker was coupled to chloromethylpolystyrene. This method proved to be better than use of the cesium salt. This new synthesis gave a polymer with appropriate structure and a good degree of substitution.
