Abstract

An Efficient Scale up Process for Synthesis of N-Arylpiperazines. -An efficient protocol for the synthesis of various substituted phenylpiperazines is presented using sulfolane as solvent. The procedure is clean, high yielding and products are obtained in high purities (>99%). It is also fast and convenient, as the final products are precipitated as the hydrochloride salts and can be isolated by filtration. -(RAVILLA, L.; SUBBA NAIDU, N.
