  摘要：

  H-β沸石促进α-氯代乙酰氯与1,2-双-三甲基甲硅烷基乙炔的反应，生成1-氯-4-（三甲基甲硅烷基）but-3-yn-2-one，经硫代乙酰胺处理后得到2 -甲基-4-[（三甲基甲硅烷基）乙炔基]噻唑。另一方面，1-脯氨酸在K 2 CO 3水溶液存在下，在Pd-Cu催化下促进了2-甲基-4-[（三甲基甲硅烷基）乙炔基]噻唑与（杂）芳基卤化物的偶联反应（改良的Sonogashira反应）。提供了一种用于合成相应的4-炔基取代的噻唑衍生物的改进方法。

  2-Methyl-6-(phenylethynyl)pyridine (3), a potent noncompetitive mGlu5 receptor antagonist widely used to characterize the pharmacology of mGlu5 receptors, suffers from a number of shortcomings as a therapeutic agent, including off-target activity and poor aqueous solubility. Seeking to improve the properties of 3 led to the synthesis of compound 9, a highly selective mGlu5 receptor antagonist that is 5-fold more potent than 3 in the rat fear-potentiated startle model of anxiety.
