formed between the corresponding ring-fluorinated 3,4-bis(benzyloxy)phenethanolamine and acetone, followed by reductive debenzylation in the presence of oxalic acid to yield crystalline neutral oxalates. The apparent beta-adrenergic potencies were determined in the isolated guinea pig atria. 2-Fluoro- and 5-fluoroisoproterenol were equipotent with (+/-)-isoproterenol, while 6-fluoroisoprotenol was virtually
