and effective procedure for the solution phase preparation of a 2-aminothiazole combinatorial library is described. Reaction, work-up and isolation of the title compounds as free bases was accomplished in a fullyautomated fashion using the Chemspeed ASW 2000 automated synthesizer. The compounds were obtained in good yields and excellent purities without any further purificationprocedure.

A simple, efficient, single step and environmentally benign synthesis of 2-aminothiazoles is described in this paper. This green protocol was catalyzed by recyclable solid supported Nafion-H using polyethylene glycol-water solvent system with improved efficiency and reduced waste production.[GRAPHICS].
