Abstract :
The development of an efficient and scalable synthetic route to prepare the selective D2 partial agonist (1) is described here. Regioselective nitration of tetrahydrobenzazepine 2, followed by reductive amination, hydrogenation, and oxidative cyclization afforded 1 in good yield, without the need of column chromatography.
