    • The present invention relates to a novel process, useful for preparing key intermediates of formula (I) in the synthesis of various compounds, among them compounds which are potent and specific antagonists of D3 receptors, in which X may be Nitrogen or Sulfur; Het means aryl or heteroaryl; each of which may be substituted by 1 to 4 groups J selected from: halogen, C1-C6 alkyl C1-C6 alkoxy, halo C1-C6 alkyl C2-C6 alkenyl, C2-C6 alkynyl, halo C1-C6 alkoxy, —C(O)R1, nitro, hydroxy, —NR2R3, cyano or a group Z; R1 is a C1-C4 alkyl —OR3 or —NR3R4; R2 is hydrogen or C1-C6 alkyl; R3 is hydrogen or C1-C6 alkyl; R is H, C1-C6 alkyl aryl, benzyl; each of which may be substituted by 1 to 4 groups J; according to the following Scheme 1: in which step a means a reaction in basic conditions of compounds (IIA) with 3-thiosemicarbazide derivatives, followed by a treatment with an inorganic base and n-propane phosphonic cyclic anhydride and final pH adjustment with inorganic acids to give compounds of formula (II).
    • 本发明涉及用于制备各种化合物的合成中的式(I)的关键中间体的新方法,其中X是可以是氮或硫的D3受体的有效和特异性拮抗剂的化合物; Het表示芳基或杂芳基; 它们各自可以被1至4个选自以下的基团取代:卤素,C 1 -C 6烷基C 1 -C 6烷氧基,卤代C 1 -C 6烷基C 2 -C 6烯基,C 2 -C 6炔基,卤代C 1 -C 6烷氧基,-C( O)R 1,硝基,羟基,-NR 2 R 3,氰基或基团Z; R 1是C 1 -C 4烷基-OR 3或-NR 3 R 4; R 2是氢或C 1 -C 6烷基; R 3是氢或C 1 -C 6烷基; R为H,C 1 -C 6烷基芳基,苄基; 其中每个可以被1至4个基团J取代; 根据以下方案1:其中步骤a表示化合物(IIA)与3-硫代氨基脲衍生物在碱性条件下的反应,然后用无机碱和正丙烷膦酸环状酸酐处理,并用无机酸进行最终pH调节 得到式(II)的化合物。
