실험 절차

A stirred suspension of 81.4 g (267 mmol) 5-iodo-2-morpholin-4-yl-pyridin-4-ylamine, 4.06 g (21.3 mmol) copper(I) iodide, 5.77 g (32.0 mmol) 1,10-phenanthroline and 174 g (533 mmol) cesium carbonate in 600 ml methanol was heated at 130° C. for 30 min in a microwave oven. The resulting mixture was then cooled to room temperature and filtered. The filtrate was concentrated in vacuo and the residue purified by flash chromatography (1/7 methanol/dichloromethane) to afford 27.7 g (50%) 5-methoxy-2-morpholin-4-yl-pyridin-4-ylamine as a dark brown crystalline solid. ES-MS m/e (%): 210 (M+H+, 100).
