The invention is substituted quinoline intermediates of the formula
wherein X is straight or branched C1-C6 alkyl, phenyl, -0-C1-C4 straight or branched alkyl or
wherein Y and Z are independently H, straight or branched C1-C6 alkyl or phenyl and
B is H, halogen, or a quaternary ammonium halide and of the formula
wherein B is a quaternary ammonium halide, useful in the synthesis of the herbicide 2-(4-isopropyl-4methyl-5-oxo-2-imidazolidinyl)-5-methoxymethylnicotinic acid and a process for preparing the herbicide intermediate 3-methoxymethyl-7- or 8-hydroxyquinoline.
本发明是式中的取代喹啉中间体
其中 X 是直链或支链 C1-C6 烷基、苯基、-0-C1-C4 直链或支链烷基或
其中 Y 和 Z 独立地为 H、直链或支链 C1-C6 烷基或苯基,且
B 是 H、卤素或季铵盐卤化物,其式如下
其中 B 为季铵盐卤化物,可用于合成除草剂 2-(4-异丙基-4-甲基-5-氧代-2-咪唑烷基)-5-甲氧基甲基烟酸和制备除草剂中间体 3-甲氧基甲基-7-或 8-羟基喹啉的工艺。
