Fluoride ion as the tetrabutylammonium salt displaces bromide in para-substituted benzyl bromides in acetonitrile or dimethylformamide. The p-bromomethyl benzoyl (BMB) group has been coupled to amino groups, including peptide amino groups, via its N-hydroxysuccinimide ester. In a subsequent step, the facile displacement of bromide by fluoride occurred under conditions compatible for use with (18)F radiotracers.
作为四丁基铵盐的氟离子在乙腈或二甲基甲酰胺中取代对取代苄基溴中的溴离子。对溴甲基苯甲酰基(BMB)基团已通过其N-羟基琥珀酰亚胺酯与氨基(包括肽氨基)偶联。在随后的步骤中,在与(18)F放射性示踪剂兼容的使用条件下,氟离子很容易取代溴离子。
