A series of 5-phenyl-3-ureidobenzazepin-2-one cholecystokinin-B (CCK-B) receptor antagonists was synthesized using Beckmann ring expansion of a suitable 4-phenyl-1-tetralone as a key step. Structure-activity relationship studies revealed the importance of the 5-phenyl group for potent and selective CCK-B affinity. Addition of an 8-methyl substituent and resolution provided the potent (CCK-B IC50 =
