Synthesis of tritium labelled BIBN 4096 – 1-piperidine-3H-carboxamide, N-[2-[[5-amino-1-[[4-(4-pyridinyl)-1-piperazinyl]carbonyl]pentyl]amino]-1-[(3,5-dibromo-4-hydroxyphenyl)methyl]-2-oxoethyl]-4-(1,4-dihydro-2-oxo-3(2 H)-quinazolinyl)-, [R-(R*,S*)]-, – a h-CGRP-antagonist for the treatment of migraine is described. Selective tritiation of a heterocyclic aromatic fragment in the presence of aromatic
氚标记的 BIBN 4096 的合成 – 1-哌啶-3H-甲酰胺,N-[2-[[5-氨基-1-[[4-(4-吡啶基)-1-哌嗪基]羰基]戊基]氨基]-1 -[(3,5-dibromo-4-hydroxyphenyl)methyl]-2-oxoethyl]-4-(1,4-dihydro-2-oxo-3(2H)-quinazolinyl)-, [R-(R* ,S*)]-, – 描述了一种用于治疗偏头痛的 h-CGRP 拮抗剂。使用固态催化交换方法成功地在 BIBN4096 前体中存在芳环的情况下对杂环芳族片段进行了选择性氚化。随后完成合成序列得到最终的[3H]BIBN4096,其比活性>170 Ci/mmol。版权所有 © 2006 John Wiley & Sons, Ltd.
