    摘要: Halogenated carboxylic ester derivatives of phenylethyl imidazole, and their method of preparation are disclosed. Radio-halogenated forms of these compounds are ideally suited for positron-imaging of the adrenal glands, as it is known that these compounds demonstrate a selective and high rate of accumulation in the adrenals. The method of preparing these derivatives proceeds by the conversion of a stable, non-radioactive intermediate having trialkylstannyl leaving groups. These intermediates are efficiently converted to the corresponding halogenated forms by substitution of the trialkylstannyl group with the halogen or radiohalogen.

    摘要: The present invention provides a process for recovering 1,3-dimethyl-2-imidazolidinone comprising extracting 1,3-dimethyl-2-imidazolidinone from an aqueous solution containing it with n-butanol in the presence of an inorganic salt to obtain n-butanol layer and, subjecting the n-butanol layer to distillation. As 1,3-dimethyl-2-imidazolidinone can be recoverable at high purity from an aqueous solution containing 1,3-dimethyl-2-imidazolidinone easily and efficiently without using alkali, the present process is industrially advantageous.

    摘要: The present invention involves a rapid synthesis of .sup.18 F-FMISO and analogs thereof. New precursors such as 1-(2'-nitro-1'-imidazolyl)-2-0-acetyl-3-0-tosylpropanol, glycerol-1,3-ditosylate-2-0-acetylate, 1-(2'-nitro-1'-imidazolyl)-2,3-0-diacetylate, are also important aspects of the invention. A further aspect of the invention is the development of a hydrophilic PET ligand to image tumor hypoxia. Erythrotosyl analogue of 2-nitroimidazone (Ts-ETNIM) was prepared from a mixture of 2-nitromidazole, ditosylthreitol and cesium carbonate at 60.degree. C. for 1 hr. Ts-ETNIM was isolated at 70% yield. �.sup.18 F!fluoroerythronitroimidazole (FETNIM) when prepared from Ts-ETNIM and K.sup.18 F/kryptofix.RTM.. The yield for �.sup.18 F!FETNIM was 26-30% (60 min, decay corrected). Results of biodistribution and PET studies indicate that �.sup.18 F!FETNIM has the potential to detect tumor hypoxia and is indicated to be less neurotoxic.
