Procedure

To a stirred solution of 4-[(dimethylamino)carbonyl]-2-(6-{[(ethylamino)carbonyl]amino}pyridin-3-yl)-1,3-thiazole-5-carboxylic acid (Example 53, 0.12 g, 3.3 mmol) in dry dimethylformamide (2 mL), HOBT (0.101 g, 6.6 mmol), N-methylmorpholine (0.108 mL, 9.9 mmol), EDC hydrochloride (0.126 g, 6.6 mmol), ethylamine (2 M in tetrahydrofuran, 0.13 mL, 3.3 mmol) were added at 0° C. and stirred overnight at room temperature. After completion of the reaction, reaction mixture was diluted with ethyl acetate (20 mL) and was washed with water (1×20 mL), 2 N hydrochloric acid (1×20 mL), and sodium bicarbonate solution (1×20 mL). The organic layer was dried, concentrated under reduced pressure and the residue was triturated with acetonitrile (1 mL). The obtained solid was filtered and dried to afford 0.018 g (20%) of the title compound as white solid. MS (APCI): 391 (M+H+) for C18H23N5O3S; NMR: δ 1.06 (t, 3H), 2.86 (s, 3H), 2.99 (s, 3H), 3.17 (q, 4H), 7.60 (d, 1H), 7.76 (br s, 1H), 8.22 (dd, 1H), 8.72 (br t, 1H), 8.78 (s, 1H), 9.52 (br s, 1H).
