  摘要：

  In the course of our program for discovery of novel DPP-IV inhibitors, a series of pyrazolo[1,5-a]pyrimidines were found to be novel DPP-IV inhibitors. We identified N-[2-({2-[(2S)-2-cyanopyrrolidin-1-yl]-2-oxoethyl}amino)-2-methylpropyl]-2-methylpyrazolo[1,5-a]pyrimidine-6-carboxamide hydrochloride (4a) and described its pharmacological profiles.
