Polymer supported bases in solution-phase synthesis. 2. A convenient method for N-alkylation reactions of weakly acidic heterocycles

Bioorg Med Chem Lett. 1998 May 5;8(9):1089-92. doi: 10.1016/s0960-894x(98)00173-5.

Abstract

A convenient solution-phase method for N-alkylation reactions of weakly acidic heterocycles employing polymer supported super base PBEMP is described. By using this method, multiple-step and chemoselective N-alkylation sequences can be carried out in a one-pot process.
