Article abstract of DOI:10.1248/cpb.42.2360

2-Methylamino-3-(1-piperidinylmethyl)-1,4 (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)-1,3-naphthoquinone (8) and/or 2-alkoxycarbonyl-3-methylamino-1,4-naphthoquinone (9), depending on the solvent used.
