Versuchsvorschrift

60 mg (0.07 mmol) of (S)-2-(1-((6-amino-5-iodopyrimidin-4-yl)amino)ethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one, 43 mg (0.11 mmol) of 2-(tributylstannyl)thiazole, 2.0 mg (0.01 mmol) of bis-triphenylphosphinepalladium(II) chloride, 4.4 mg (0.02 mmol) of copper (I) iodide and 32 μl (0.23 mmol) of triethylamine in dimethylformamide (1.5 mL) were heated to 120° C. for 20 minutes with microwave irradiation under nitrogen atmosphere. The reaction mixture was filtered through Celite® and washed with methanol. The solvent of the filtrates were evaporated in vacuum and the residue was dissolved in ethyl acetate and washed with brine, dried over magnesium sulphate, filtered and the solvent was removed. The product was purified first by reverse phase chromatography (C-18 silica from Waters®, water/1:1 acetonitrile-methanol as eluents [0.1% v/v formic acid buffered] 0% to 100%) and then by preparative HPLC (Waters XBridge C18 OBD column, mixture of eluents NB from 50% B to 65% B, in a 10 min. gradient) to give 4 mg (13% yield) of the title compound.
