Synthesis of 5-Amino-1H-pyrazole-4-carbonitriles from N-Tosylhydrazones and Its Application in the Preparation of Ibrutinib

A facile method for preparing 5-amino-1H-pyrazole-4-carbonitriles was developed. The reaction exhibited compatibility to various substrates, and different 5-amino-1H-pyrazole-4-carbonitriles were prepared efficiently. Ibrutinib was prepared under palladium-free conditions in six steps in 32.7% overall yield.
