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 18F radiotracers
作为四丁基铵盐的氟离子取代了乙腈或二甲基甲酰胺中对位取代的苄基溴中的溴化物。对溴甲基苯甲酰基(BMB)基团已经通过其N-羟基琥珀酰亚胺酯与包括肽氨基在内的氨基偶联。在随后的步骤中,在适合与18 F放射性示踪剂兼容的条件下,发生了氟化物对溴化物的轻松置换。
