実験手順

3,6 Dichloropyridine-2-carboxylic acid (0.55 g, 2.86 mmol), morpholine (1.37 g, 15.7 mmol) and N,N dimethylacetamide (1.37 mL) were combined and stirred for 24 h at 80° C. An additional volume of morpholine (1.39 g, 15.7 mmol) was added and heating continued for 40 hours more. After cooling the DMA was removed in the presence of toluene. The residue was dissolved in water and extracted with ether to remove excess morpholine. The aqueous was acidified to pH=2 and the product extracted into ether. Crystallization from water gave a white solid, 369 mg (53% yield). 1H NMR (CD3OD): δ 3.52 (t, 4H), 3.78 (t, 4H), 6.97 (d, 1H), 7.65 (d, 1H). LC-MS, M+H: 243.
