참여 물질

반응 단계

To a 25 mL round bottomed flask with a stirring bar, reflux condenser and a nitrogen inlet was added 5-bromo-8-hydroxy-[1,6]naphthyridine-7-carboxylic acid methyl ester (0.511 g, 1.81 mmol) dry toluene (12.5 mL) and 2-methylthiobenzylamine (0.346 g, 2.26 mmol). This mixture was heated at reflux for 24 h. The mixture was cooled to ambient temperature and the toluene was removed in vacuo. The residue was triturated with a little Et2O/hexane, collected on a frit and dried in vacuo to give 8-hydroxy-5-bromo-[1,6]naphthyridine-7-carboxylic acid 2-methylsulfanylbenzylamide as a crystalline solid.
