A mixture of methyl 4-[1-hydroxy-1-(1H-pyrazol-4-yl)ethyl]benzoate (17 mg, 0.053 mmol), N-(3-bromo-5-methylphenyl)-4-(trifluoromethyl)pyrimidin-2-amine (13 mg, 0.053 mmol), copper(I) iodide (1 mg, 0.005 mmol), N1,N2-dimethylethane-1,2-diamine (0.47 mg, 0.005 mmol), and cesium carbonate (52 mg, 0.16 mmol) in 1,4-dioxane (2 mL) was stirred at 130° C. for 50 minutes. After being cooled to room temperature, the mixture was diluted with ethyl acetate and washed with brine. The organic layer was concentrated and the residue was purified by preparative thin layer chromatography to afford methyl 4-{1-hydroxy-1-[1-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1H-pyrazol-4-yl]ethyl}benzoate. MS ESI calc'd. for C25H23F3N5O3 [M+H]+ 498. found 498. 1H NMR (400 MHz, CDCl3): δ 8.66 (s, 1H), 8.02-8.06 (m, 3H), 7.78 (s, 1H), 7.59-7.63 (m, 3H), 7.51 (s, 1H), 7.18 (s, 1H), 7.06 (s, 1H), 3.92 (s, 3H), 3.79 (s, 1H), 3.49 (s, 1H), 2.41 (s, 3H), 1.97 (s, 3H).
