4-Methylmorpholine → N-{2-[4-(3-Pyrrolidin-1-yl-propane-1-sulfonyl)-phenylamino]-pyrimidin-5-yl}-3-(3-trifluoromethyl-benzoylamino)-benzamide

To a solution of intermediate 5 (Example 9) (240 mg, 0.8 mmol) in anhydrous CH2Cl2 (15 mL), 2-chloro-4,6-dimethoxy-1,3,5-triazine (170 mg, 1 mmol) and 4-methylmorpholine (160 mg, 1.6 mmol) were added. After the reaction mixture was stirred at room temperature for 75 minutes, intermediate 2 (Example 3) (100 mg, 0.3 mmol) in anhydrous DMF (2.5 mL) was added into the solution. The solution was stirred under argon for overnight. The residue was dissolved in CH2Cl2 (20 mL) and washed with aqueous saturated NaHCO3 solution (20 mL). The aqueous layer was extracted with CH2Cl2 (50 mL). The combined organic phase was dried (Na2SO4) and the solvent was removed. The crude product was purified by silica gel column with CHCl3 to 10% CH3OH/CHCl3 as eluents to give the final product as a pale yellow solid (100 mg, 19%).
