Reaction Steps

N-(3-Methyl-5-(1H-pyrazol-4-yl)phenyl)-4-(trifluoromethyl)pyrimidin-2-amine (34 mg, 0.11 mmol), 3-bromo-2-methylprop-1-ene (11 μl, 0.11 mmol), cesium carbonate (69 mg, 0.21 mmol) and DMA (210 μL) were combined in a vial and stirred at 100° C. for 1.25 hours. The reaction mixture was diluted with EtOAc, washed with aqueous sodium bicarbonate, then brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to afford crude N-(3-methyl-5-(1-(2-methylallyl)-1H-pyrazol-4-yl)phenyl)-4-(trifluoromethyl)pyrimidin-2-amine as a yellow oil. MS ESI calcd. for C19H19F3N5 [M+H]+ 374. found 374.
