使N-氨基吡啶基酮盐与甲酰胺反应,得到杂芳族吡啶并[ 2,1- f ] [1,2,4]三嗪鎓盐。在水存在下储存这些产物时,已经观察到形成共价水合物。相同的起始化合物与氨基甲酸酯反应生成3-氯吡啶并[2,1 - f ] [1,2,4]三嗪鎓盐,其易于与仲胺反应以提供3-氨基衍生物。2-甲酰基氨基甲基-和甲氨基苄基吡啶的类似的闭环反应允许合成部分还原的3,4-二氢吡啶并[2,1 - f ] [1,2,4]三嗪化合物。该环化程序也用于相关的嘧啶基[ 2,1- f ] [1,2,4]三嗪鎓盐的合成。

The present invention relates to Bicyclic Heterocycle Derivatives of formula (I), compositions comprising a Bicyclic Heterocycle Derivative, and methods of using the Bicyclic Heterocycle Derivatives for treating or preventing obesity, diabetes, a metabolic disorder, a cardiovascular disease or a disorder related to the activity of GPR1 19 in a patient.
Imidazo[1,5-a]pyridines in acetic acid solution are readily nitrated by nitric acid–sulphuric acid, although in some instances treatment of the base hydrogensulphate with nitric acid–acetic acid is preferred. Nitration occurs most readily in the 1-position, but 3-nitration occurs if the 1-position is already substituted.
乙酸溶液中的咪唑并[1,5- a ]吡啶很容易被硝酸-硫酸硝化,尽管在某些情况下,优选用硝酸-乙酸处理碱式硫酸氢盐。硝化作用最容易在1位发生,但如果1位已经被取代,则发生3位硝化。

The direct benzylicarylation of N-benzylxanthone imine with aryl chloride proceeds under palladium catalysis, yielding the corresponding coupling product. The product is readily transformed to benzhydrylamine. Taking into consideration that the imine is readily available from benzylic amine, the overall transformation represents a formal cross-coupling reaction of aryl halide with alpha-aminobenzyl
