Reaction Steps

In a pressure tube with one end sealed, add 192 mg step 3 product, 3-ethynyl-4-methyl-N-(3-(4-methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)phenyl)benzamide (0.5 mmol), 107 mg Step 4 product, 5-bromo-N-cyclopropylpyrimidin-2-amine (0.5 mmol), 19 mg CuI (0.1 mmol), 2.2 mg Pd(OAc)2 (0.01 mmol), 2.8 mg PCy3 (0.01 mmol) 3.0 mL DMF, 193 mg DIPEA (1.5 mmol), after nitrogen replacement, the solution is heated to 60° C. for 12 h. After cooling to room temperature, the solid is filtered off by 2 cm silical gel column and washed by ethyl acetate for three times, and the solution was concentrated by vacuum evaporation for 193 mg desired product (75%).
