A new radiosynthetic protocol for the preparation of [(11)C]aryl nitriles has been developed. This process is based on the direct reaction of in situ prepared L·Pd(Ar)X complexes (L = biaryl phosphine) with [(11)C]HCN. The strategy is operationally simple, exhibits a remarkably wide substrate scope with short reaction times, and demonstrates superior reactivity compared to previously reported systems
Provided is a process for the preparation of vilazodone, its intermediate compounds and pharmaceutically acceptable salts thereof. Solvates of vilazodone and processes for their preparation are also provided. A process for the preparation of amorphous vilazodone hydrochloride is further provided.
