    • The present invention is directed to a novel method of preparing of 2,4,8-trisubstituted pyrido[2,3-d]pyrimidin-7-one pharmacophores of Formula (II) wherein G1 is CH2 or NH: G2 is CH or nitrogen; Rx is chloro, bromo, iodo, or O—S(O)2CF3; Rg is a C1-10alkyl; m is 0, or an integer having a value of 1, or 2; R3 is a C1-10alkyl, C3-7cycloalkyl, C3-7cycloalkyl C1-10alkyl, aryl, arylC1-10alkyl, heteroaryl, heteroarylC1-10alkyl, heterocyclic or a heterocyclylC1-10alkyl moiety, and wherein each of these moieties may be optionally substituted. which comprises reacting a compound of the formula: wherein Ry is chloro, bromo, iodo, O—S(O)2CF3; and Rg is a C1-10alkyl; with a olefin forming reagent in a suitable base to yield a compound of Formula (II), wherein m=0 and oxidizing the sulphur as necessary or desired.
    • 本发明涉及一种制备式(II)的2,4,8-三取代吡啶并[2,3-d]嘧啶-7-酮药效团的新方法,其中G1是CH 2 或NH:G2为CH或氮; Rx是氯,溴,碘或O-S(O)2 CF 3。 R 1是C 1-10烷基; m为0,或值为1或2的整数; R 3是C 1-10烷基,C 3-7环烷基,C 3-7环烷基C 烷基,芳基,芳基C 1-10烷基,杂芳基,杂芳基C 1-10烷基,杂环基或杂环基C 1 -10个烷基部分,并且其中这些部分中的每一个可以是任选取代的。 其包括使下式化合物:其中R y是氯,溴,碘,O-S(O)2 CF 3 3; 且R g为C 1-10烷基; 与合适的碱中的烯烃形成试剂反应,得到式(II)的化合物,其中m = 0并根据需要氧化硫。
