Phenyl N-phenylcarbamate

In the ripretinib synthesis route, it serves as an activated phenyl carbamate/urea precursor that enables formation of the phenylurea linkage, a critical structural motif of the API. Through reaction with the appropriate amine-containing intermediate, phenyl N-phenylcarbamate facilitates construction of the final urea functionality, making it an important building block in the late-stage assembly of ripretinib. Phenyl N-phenylcarbamate serves as a key synthetic intermediate in the manufacture of the active pharmaceutical ingredient ripretinib.
