Versuchsvorschrift
A solution of N-(3-fluorophenyl)-2-{4-[(7-hydroxyquinazolin-4-yl)amino]-1H-pyrazol-1-yl}acetamide (0.590 g, 0.97 mmol), cesium carbonate (1.95 g, 5.98 mmol) and tert-butyl (2S)-2-{[(methylsulphonyl)oxy]methyl}pyrrolidine-1-carboxylate (0.325 g, 1.16 mmol) in dimethylacetamide (10 ml) was heated at 80° C. for 18 hours. The mixture was poured into water and extracted with ethyl acetate. The organic layer was separated, dried over magnesium sulphate and evaporated in vacuo to leave a brown oil which was purified by silica gel chromatography. Elution with 5 to 7% methanol in dichloromethane gave tert-butyl (2S)-2-[({4-[(1-{2-[(3-fluorophenyl)amino]-2-oxoethyl}-1H-pyrazol-4-yl)amino]quinazolin-7-yl}oxy)methyl]pyrrolidine-1-carboxylate (0.332 g, 61% yield) as a light brown solid.
