tris(2-aminoethyl)amine and methyl isocyanate are described. These polymeric reagents are used to quench excess reactants and remove known impurities from the crude reaction products obtained from the solution-phase, parallel syntheses of ureas, thioureas, sulfonamides, amides, and pyrazoles. In conjunction with the use of other polymeric reactants during the course of a reaction, the addition of polymer-supported
