Versuchsvorschrift

In a 16×120 mm resealable pyrex tube, 5-ethynylpyrimidin-2-amine (0.080 g, 0.67 mmol), (R)—N-(2-(3-(tert-butyldimethylsilyloxy)piperidin-1-yl)-5-(trifluoromethyl)phenyl)-2-fluoro-5-iodobenzamide (0.210 g, 0.34 mmol), Bis(triphenylphosphine)palladium(II) dichloride (0.012 g, 0.017 mmol), and Copper(I) iodide (0.0032 g, 0.017 mmol) were taken up in CH3CN and Triethylamine (0.71 ml, 5.1 mmol) was added, and the tube was flushed with nitrogen. The tube was sealed and the reaction heated to 70° C. overnight. The reaction was cooled, and transferred to a 50 mL RBF with EtOAc. The mixture was concentrated in vacuo, and the resulting solid was treated with 10% MeOH in CH2Cl2 and adsorbed onto 1.5 g silica gel and passed through a Redi-Sep® pre-packed silica gel column (40 g) eluting with 0-60% EtOAc/hexane. The product-containing fractions were concentrated to afford (R)-5-(2-(2-aminopyrimidin-5-yl)ethynyl)-N-(2-(3-(tert-butyldimethylsilyloxy)piperidin-1-yl)-5-(trifluoromethyl)phenyl)-2-fluorobenzamide as an off-white solid.
