実験手順
10.45 g (0.0791 mol; 1.2 eq) of 2,5-dimethoxy-tetrahydrofuran and 12.00 g (0.0791 mol; 1.2 eq) of 4chloropyridine hydrochloride are stirred for 10 minutes in 300 cm3 of dioxane. 11.15 g (0.0659 mol) of 2-amino-6methoxy-3-nitropyridine are added and the solution is brought to reflux for 4 h. The dioxane is evaporated under reduced pressure.
