The process development and multikilogram preparation of a TRPV1antagonist, 1, is described. Pyrido[2,3-b]pyrazine 1 was prepared in a convergent manner by the coupling of two key fragments, glyoxal 2 and diamine 3. Glyoxal 2 was synthesized in six chemical steps in 20% overall yield, the key step being a challenging Grignard reaction to install the glyoxalate moiety. Diamine 3 was also prepared in
描述了TRPV1拮抗剂1的工艺开发和多千克制备。通过两个关键片段,乙二醛2和二胺3的偶联,以收敛的方式制备了吡咯并[2,3- b ]吡嗪1。乙二醛2是通过六个化学步骤合成的,总产率为20%,关键步骤是安装乙二醛部分的极具挑战性的格氏反应。二胺3还可以通过六个化学步骤以46%的总收率制备,利用区域选择性亲核芳族取代获得关键的硝基二胺中间体19。
