    [11C]raclopride from [11C]methyl triflate. Conditions for the radiolabelling were optimized to obtain a simple and reproducible procedure suitable for automation. [11C]Raclopride was prepared with an average radiochemical yield of 55–65% (decay corrected, based on starting [11C]methyl triflate) in a total synthesis time (including purification and formulation of product) of 35 min. The radiolabelling procedure used

    A new radiolabeling method using a microreactor was developed for the rapid synthesis of [11C]raclopride. A chip bearing a Y-shaped mixing junction with a 200 µm (width)×20 µm (depth)×250 mm (length) flow channel was designed, and the efficiency of O-[11C]methylation was evaluated. Dimethyl sulfoxide solutions containing the O-desmethyl precursor or [11C]CH3I were introduced into separate injection ports by infusion syringes, and the radiochemical yields were measured under various conditions. The decay-corrected radiochemical yield of microreactor-derived [11C]raclopride reached 12% in 20 s at 25°C, which was observed to increase with increasing temperature. In contrast, batch synthesis at 25°C produced a yield of 5%: this indicates that this device could effectively achieve O-[11C]methylation in a shorter period of time. The microreactor technique may facilitate simple and efficient routine production of 11C-labeled compounds via O-[11C]methylation with [11C]CH3I.
    为快速合成 [11C]raclopride 开发了一种使用微反应器的放射性标记新方法。该方法设计了一个带有 Y 形混合结的芯片,其流道为 200 微米(宽)×20 微米(深)×250 毫米(长),并对 O-[11C]甲基化的效率进行了评估。通过输液注射器将含有 O-去甲基前体或 [11C]CH3I 的二甲基亚砜溶液分别注入不同的注入口,并在不同条件下测量放射化学产率。在 25°C 温度下,微反应器衍生的[11C]拉克必利的衰变校正放射化学产率在 20 秒内达到 12%,而且随着温度的升高而增加。相比之下,在 25°C 温度下批量合成的产率为 5%:这表明该装置可以在更短的时间内有效实现 O-[11C]甲基化。该微反应器技术可通过[11C]CH3I 的 O-[11C]methylation 简单高效地实现 11C 标记化合物的常规生产。

    日期:2004.12.31
    An improved synthesis of [C-11]raclopride is reported. The precursor desmethyl-raclopride was synthesized from 3,5-dichloro-2,6-dimethoxybenzoic acid and (S)-(-)-2-aminoethyl-1-ethylpyrrolidine via a straightforward, four-step synthetic approach with 29% overall chemical yield. [C-11]Raclopride was prepared by O-[C-11]methylation of the precursor with [C-11]methyl triflate and purification with a semi-preparative HPLC method in 20-34% radiochemical yield, based on [C-11]methyl bromide, decay corrected to end of bombardment (EOB).
