Reaction Steps

To a degassed mixture of 4-chloro-N-(1-methyl-1H-pyrazol-4-yl)-5-(trifluoromethyl)pyrimidin-2-amine A74 (0.178 g, 0.640 mmol), 1-(2-ethynylphenyl)cyclopropanecarboxamide K6 (0.172 g, 0.928 mmol), PdCl2(PPh3)2 (0.005 g, 0.007 mmol), t-Bu3PH.BF4 (0.005 g, 0.02 mmol) and copper(I) iodide (0.003 g, 0.02 mmol) in DMF (8.0 mL) was added DIPEA (0.33 mL, 1.9 mmol). The mixture was heated in the microwave for 2×20 minutes at 100° C. before being concentrated under reduced pressure. Purification by silica gel column chromatography (Isolera, 0-100% EtOAc petroleum benzine 40-60° C. then 0-20% MeOH in EtOAc) gave the title compound A75 (0.120 g, 44%). LCMS-D: rt 3.30 min; m/z 427.2 [M+H]+.
