Reaction Steps

To a solution of [3-(3-methylcarbamoyl-1H-indazol-5-ylcarbamoyl)-pyrrolidin-1-yl]-acetic acid (15 mg, 0.043 mmol, prepared by a procedure similar to that of Example 98 using the indazole of Example 85 instead of indazole 65) and HOBt (7 mg, 0.052 mmol) in DMF (0.5 mL) at 0° C., EDCl (10 mg, 0.052 mmol) was added and the resulted reaction mixture was stirred at this temperature for 0.5 hour. To this solution was added 2-(2-piperazin-1-yl-thiazol-5-yl)-pyrimidine (18 mg, 0.052 mmol) made from previous step, followed by DIEA (7 μL). The reaction was stirred at 0° C. for 1 hour and was gradually warm up to room temperature and was continuously stirred for overnight. Ethyl acetate (5 mL) was then added, followed by water (10 mL). The organic layer was collected, dry over sodium sulfate, evaporate of solvent and residue was purified using prep-HPLC. To the solution obtained from HPCL, HCl (1N, 2 mL) was added and the solution was brought to dryness under vacuum. The formed residue was then dissolved in acetonitrile/water (3:1) and was lyophilized to give desired product (10 mg, 38% yield) as hydrochloride salt.
