Procedure

A degassed mixture of tert-butyl 4-((4-chloro-5-(trifluoromethyl)pyrimidin-2-yl)amino)-1H-pyrazole-1-carboxylate A61 (0.373 g, 1.03 mmol), 2-(2-ethynylphenyl)propanamide K7 (0.452 g, 2.40 mmol), PdCl2(PPh3)2 (0.015 g, 0.02 mmol), t-Bu3PH.BF4 (0.011 g, 0.038 mmol) and CuI (0.007 g, 0.04 mmol) in 1,4-dioxane (6.0 mL) and DIPEA (0.90 mL, 5.2 mmol) was heated in the microwave at 100° C. for 30 minutes. The mixture was concentrated under reduced pressure and purified using silica gel column chromatography (0-100% EtOAc in petroleum benzine 40-60° C.) to give the title compound A62 (0.309 g, 58%). LCMS-D: rt 3.533 min; m/z 502.2 499.2 [M−H]−.
