Tritium labelled FPL 64176 (1, methyl 2,5-dimethyl-4-2-(phenylmethyl)benzoyl]-1H-pyrrole-3-carboxylate), a potent calcium channel activator with insulinotropic properties was synthesized from the corresponding bromo derivative (3) using tritium gas and Pd/C catalyst. (3) was in turn prepared from methyl 2,5-dimethylpyrrole-3-carboxylate (4) in a one pot procedure. The specific activity of [3H]FPL 64176 was 38 mCi/mmol and radiochemical purity >98%.
用氚标记的FPL 64176(1,甲基2,5-二甲基-4-2-(苯基甲基)苯甲酰]-1H-吡咯-3-羧酸酯)是一种有效的钙通道激活剂,具有促胰岛素分泌特性。它是通过使用氚气和Pd/C催化剂从相应的溴衍生物(3)合成的。(3)则是通过一种锅法从甲基2,5-二甲基吡咯-3-羧酸酯(4)制备的。[3H]FPL 64176的特定活性为38 mCi/mmol,放射化学纯度>98%。
