The present invention pertains to methods for preparing 5- and 6-benzyl functionalized quinoxalines. In a first embodiment, the method comprises contacting an aqueous suspension of a 5- and 6-halomethyl quinoxaline with a water-soluble nucleophile. In a second embodiment, the method comprises contacting a 5- and 6-halomethyl quinoxaline with an organic solvent-soluble nucleophile in an inert polar organic solvent. In a third embodiment, the method comprises contacting a 5- and 6-halomethyl quinoxaline in an organic solvent with an aqueous solution of a water-soluble nucleophile in the presence of a phase transfer catalyst.
本发明涉及制备 5-和 6-苄基官能化
喹喔啉的方法。在第一个实施方案中,该方法包括将 5-和 6-苄基
