130 °C

A mixture of 2,6-dichloro-4-methoxypyridine (1.0 equiv.) and morpholine (20 equiv.) were heated to 130° C. for 40 min in the microwave. The reaction mixture was centrifuged and the soluble portion was removed from solids. Water was added to the soluble portion which resulted in precipitation of product. This mixture was centrifuged and the soluble portion was discarded. The remaining solids were partitioned between water and EtOAc. The organic phase was washed with brine and dried over sodium sulfate. The solution was concentrated and dried under vacuo to give 4-(6-chloro-4-methoxypyridin-2-yl)morpholine in 43% yield. LCMS (m/z) (M+H)=229.1, Rt=0.76 min.
