    摘要: A process for preparing 2(4-fluorophenyl).alpha.-methyl-5-benzoxazole acetic acid starting from 4-hydroxy-3-amino-phenylacetic acid, which is firstly reacted with 4-fluorobenzoyl chloride, and the product obtained is reacted with phosphoric acid; the 2(4-fluorophenyl)5-benzoxazole acetic acid obtained in this manner is esterified with ethyl alcohol, and the ester is treated with diethyloxalate; the ethyl 2(4-fluorophenyl)5-benzoxazole oxalacetate obtained is reacted with formaldehyde and potassium carbonate to obtain ethyl 2(4-fluorophenyl)5-benzoxazole acrylate, which is hydrolysed to obtain the corresponding acid, from which the 2(4-fluorophenyl).alpha.-methyl-5-benzoxazole acetic acid is obtained by hydrogenation.

    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.
