Abstract
The synthesis of a new polymer-supported coupling reagent derived from 1- hydroxybenzotriazole is described. An aminomethylated polystyrene was functionalized by reaction with 3-nitro-4-chlorobenzenesulfonyl chloride (2) followed by treatement with hydrazine hydrate, to give the polymeric N-benzyl-1-hydroxybenzotriazole-6-sulfonamide (4). The polymeric reagent 4 was shown to be highly efficient for the synthesis of amides. ...
