Reaction Steps

5-Chloro-4-methoxypyridin-2,3-diamine (0.498 g, 2.9 mmol) was dissolved in DMF (7 ml). Iron(III)chloride hexahydrate (0.06 g, 0.2 mmol) was added and the mixture heated to is 80° C. 4-(2-Hydroxyethoxy)benzaldehyde (0.48 g, 2.9 mmol) dissolved in DMF (4 ml) was added dropwise, and the reaction mixture was heated at 110° C. for 11 h with air bubbling through the solution. The solvent was removed by evaporation, the solid residue was dissolved in warm methanol and filtered through a short plug of silica gel. Following evaporation and recrystallization (methanol), the title compound was isolated (0.26 g, 28%).
