Procedure

Ethyl 6-chloronicotinate (5.0 g) and morpholine (10 ml) were mixed and then heated to 100° C. In less than 5 minutes at this temperature, a thick paste formed. Acetonitrile (15 ml) was added and heating was continued overnight at 90° C. The mixture was cooled, diluted with water and extracted with ethyl acetate. The organic layer was dried and concentrated in vacuo to give ethyl 6-morpholin-4-ylpyridine-3-carboxylate as a white solid. NMR (300 MHz, CDCl3: 8.80 (s, 1H), 8.05 (d, 1H), 6.60 (d, 1H), 4.35 (q, 2H), 3.80 (m, 4H), 3.65 (m, 4H), 1.35 (t, 3H).
