The acid-catalyzed cleavage of the tert-butoxycarbonyl group Is the best method to form the parent benzazepinone. Other methods used have been the Pd/C hydrogenolysis of a benzyloxycarbonyl group,and zinc mediated reductive cleavage of trichloroethoxy and trichloro-tert-butoxy carbonyl groups. ... [Pg.74]
