2-(Aminomethyl)phenols, a new class of saluretic agents. 5. Fused-ring analogs

A number of bicyclic ring-fused analogues of 2-(aminomethyl)phenol were synthesized and tested orally in rats and intravenously in dogs for saluretic and diuretic effects. Of the 15 alicylic, aromatic, and heterocyclic ring-fused compounds tested, only 2-(aminomethyl)-4-chloro-1-naphthalenol hydrochloride (2) and 7-(aminomethyl)-6-hydroxy-5,8-dimethyl-1,2,3,4-tetrahydronaphthalene hydrochloride (6) displayed a high order of activity.
