An efficient scale up process for synthesis of N-arylpiperazines
摘要:
An efficient protocol for the synthesis of various substituted phenylpiperazines was developed using sulfolane as solvent. The protocol was clean, high yielding and products were obtained in high purities (>= 99%). It was also fast and convenient, as the final products were precipitated as hydrochloride salts and could be obtained by filtration. Sulfolane, an aprotic, dipolar, high boiling and recoverable solvent was used as a substitute for common organic solvents. (C) 2015 Elsevier Ltd. All rights reserved.
