2-Methylamino-3-(1-piperidinylmethyl)-1, 4-naphthoquinone (7) was prepared via several steps from 2-methyl-1, 4-naphthoquinone (vitamin K3, 3). The quinone (7) was photochemically oxidized to 2-methylamino-3-(1-piperidinylcarbonyl)-1, 4-naphthoquinone (8) and/or 2-alkoxycarbonyl-3-methylamino-1, 4-naphthoquinone (9), depending on the solvent used.
2-甲基氨基-3-(1-哌啶基甲基)-1, 4-萘醌 (7) 由 2-甲基-1, 4-萘醌(维生素 K3, 3)通过几个步骤制备。醌(7)被光化学氧化成2-甲基氨基-3-(1-哌啶基羰基)-1, 4-萘醌(8)和/或2-烷氧基羰基-3-甲基氨基-1, 4-萘醌(9),具体取决于与所使用的溶剂有关。
