Procedure

Using an analogous procedure to that described in Example 2 except that the reaction mixture was heated to 80° C. for 16 hours, 6-chloropyridine-3-carbonyl chloride was reacted with N-(3-amino-4-chlorophenyl)-2-morpholinopyridine-4-carboxamide. The reaction mixture was evaporated and the residue was triturated under water. The resultant solid was isolated, washed with a saturated aqueous sodium bicarbonate solution and dried in a vacuum oven. The material so obtained was purified by column chromatography on an ion exchange column (isolute CBA column from International Sorbent Technology Limited, Hengoed, Mid-Glamorgan, UK) using methanol as eluent. There was thus obtained the title compound (0.493 g) in 58% yield; NMR Spectrum: (DMSOd6) 3.51 (m, 4H), 3.71 (m, 4H), 7.09 (d, 1H), 7.23 (s, 1H), 7.55 (d, 1H), 7.71 (d, 2H), 8.06 (s, 1H), 8.27 (d, 1H), 8.35 (d, 1H), 8.96 (s, 1H), 10.39 (s, 1H), 10.49 (s, 1H); Mass Spectrum: M+H+ 472.
