Procedure

5-Bromo-4-cyclohexylamino-pyrimidine-2-carbonitrile (0.19 mmol) and chloromethyl-4-prop-2-ynyloxy-benzene (0.22 mmol) in DMF (5 ml) are treated with triethylamine (0.56 mmol), copper (I) iodide (0.019 mmol), and dichlorobis(triphenylphosphine)palladium(II) (0.0093 mmol) at room temperature. The mixture is stirred for 2 h at 65° C., poured into an ice water, extracted with AcOEt. The organic layer is washed with brine, dried over magnesium sulfate and concentrated. The crude product is purified by silica gel column chromatography to give the product in 21% yield. Rf=0.75 (n-hexanes:AcOEt=1:2). 1H-NMR (400 MHz, CDCl3) δ 1.02-1.48 (m, 5H), 1.57-1.78 (m, 3H), 1.80-1.98 (m. 2H), 3.94-4.04 (m, 1H), 4.61(s, 2H), 5.03 (s, 2H), 5.38 (d, 1H), 7.04 (d, 2H), 7.41 (d, 2H), 8.21 (s, 1H).
