摘要:
The invention discloses 1-tertiary-butyl-3-morpholino-3-phenyl-2,1-benzisoxazolines having pharmacological activity in animals and useful, for example, as hypolipidemic agents. The compounds may be prepared by reacting a 1-tertiary-butyl-3-phenyl-2,1-benzisoxazolium quaternary salt, e.g., 1-tertiary-butyl-3-phenyl-2,1-benzisoxazolium tetrafluoroborate with morpholine. The 1-tertiary-butyl-3-phenyl-2,1-benzisoxazolium quaternary salt may be prepared by reaction of a corresponding 3-phenyl-2,1-benzisoxazole with tertiary-butanol in the presence of a strong inorganic acid.
