실험 절차

4-Fluoro-3-{[7-(2-methyl-2H-pyrazol-3-yl)-imidazo[1,2-a]pyridine-3-carbonyl]-amino}-benzoic acid (step 2) (450 g, 1.19 mol), EDC.HCl (454.8 g, 2.372 mol) and HOBt (181.6 g, 1.186 mol) in DMF (3.2 L) at 25° C. were stirred for 1.5 hr. The reaction was monitored by HPLC. To the reaction mixture was dropwise added cis 2-(2,6-dimethyl-piperidin-1-yl)-ethylamine (222.5 g, 1.423 mol) over 10 min and stirring continued for 30 min. To the reaction mixture was dropwise an aqueous solution of Na2CO3 (5%, 6 L) over 120 min and the resulting solid was collected by filtration and washed with water (5 L). To the solid was added ethanol (5 L) followed by heating to 70° C. to obtain a clear solution. Water (1.5 L) was dropwise added at 70° C. and stirred for 30 min. The clear solution was slowly cooled to 25° C. over 2 hr. The solid was filtered, washed with ethanol (500 mL) and dried under vacuum at 50° C. overnight to afford the title compound as a white solid;
