Abstract A synthesis of terfenadine carboxylate, 1, a metabolite of terfenadine 2, is described. In the key step, the sodium salt of 2-(4-bromophenyl)-2-methylpropionic acid, 7, was lithiated via a metal-halogen exchange using t-BuLi and subsequently condensed with 4-[4-(hydroxydiphenylmethylpiperidin-1-yl]butyraldehyde, 5, to afford terfenadine carboxylate, 1.
摘要 描述了特非那定 2 的代谢物特非那定羧酸酯 1 的合成。在关键步骤中,2-(4-溴苯基)-2-甲基丙酸的钠盐 7 通过使用 t-BuLi 的金属-卤素交换锂化,随后与 4-[4-(羟基二苯基甲基哌啶-1-基]丁醛,5,得到特非那定羧酸盐,1。
