A novel method to enable SNAr reaction of aminopyrrolopyrazoles
摘要:
Here we report mild, environmentally-friendly reaction conditions which enable the addition-elimination SNAr reaction between weakly reactive substrates-an aminopyrrolopyrazole template and several substituted pyrimidines. The method was developed during our efforts to synthesize a series of novel P21-activated kinase (PAK) inhibitors. (c) 2011 Elsevier Ltd. All rights reserved.
