Procedure

To a solution of Morpholine (5.0 equiv.) and 4-bromo-2,6-dichloropyridine (1.0 equiv.) in DMF (0.275 M) was added cesium carbonate (2.0 equiv.). The mixture was heated at 100° C. for 45 hours. LCMS analysis indicated formation of several products including the desired (M+H=288, Rt=0.87 min). The reaction mixture was then concentrated in vacuo to yield a glassy foam. Water was then added, and the mixture was extracted with ethyl acetate, and the combined extracts were washed with brine, dried over magnesium sulfate, filtered, and concentrated. The residue was chromatographed via ISCO to provide 4,4′-(4-bromopyridine-2,6-diyl)dimorpholine (44%, 80% purity by LC) as a white crystalline solid. LCMS (m/z) (M+H)=288.0, Rt=0.87 min
