7-Azaindole, as a bioisostere of indole or purine, is widely used in drug development. Among them, 1H-pyrrolo[2,3-b]pyridine-6-carbonitrile is a key intermediate for the synthesis of a class of selective cyclin-dependent kinase (CDK) 7 inhibitors. Among mammalian CDKs, CDK7 has a unique integrated kinase activity that helps regulate the cell cycle and gene transcription. 1H-pyrrolo[2,3-b]pyridine-6-carbonitrile can be prepared using 7-azaindole-7-oxide as a raw material.
