The present invention relates to a novel process for the manufacture of certain substituted aminopyridines having Formula (I)
or a tautomer or salt thereof, wherein
R1 is selected from hydrogen, halogen, C1-4alkoxy, C1-4alklthio, C1-4alkyl, C3-5cycloalkyl, for example R1 is halogen such as chloro;
R2 is C1-4alkyl, for example methyl, ethyl, i-propyl, n-propyl or butyl (any isomer), such as methyl; and
R3 is selected from hydrogen, C1-4alkoxy, C1-4alkylthio, C1-4alkyl, C3-5cycloalkyl, for example C1-4alkyl such as methyl, ethyl, i-propyl, n-propyl or butyl (any isomer), for example methyl;
crystalline forms thereof as well as chemical intermediates suitable for use in performing the process.
本发明涉及一种用于制造具有化学式(I)的某些取代氨基吡啶的新型方法或其互变异构体或盐,其中R1从氢、卤素、C1-4烷氧基、C1-4烷硫基、C1-4烷基、C3-5环烷基中选择,例如R1为卤素如氯;R2为C1-4烷基,例如甲基、乙基、异丙基、正丙基或丁基(任何异构体),例如甲基;R3从氢、C1-4烷氧基、C1-4烷硫基、C1-4烷基、C3-5环烷基中选择,例如C1-4烷基如甲基、乙基、异丙基、正丙基或丁基(任何异构体),例如甲基;以及适用于执行该方法的化学中间体的结晶形式。
