Vorschrift

To 13 mg (0.21 mmol) 2-fluoro-ethanol in 0.5 mL 1,4-dioxane are added 34 mg (0.10 mmol) 2-[4-(2-chloro-pyrimidin-5-ylethynyl)-phenyl]-N-ethyl-propionamide (XVIII.1) in 1 mL 1,4-dioxane, followed by 12 mg (0.30 mmol) sodium hydride (60% in mineral oil). The mixture is stirred at rt for 12 h. After that time, the solvent is evaporated and the residue s purified by HPLC (preparative column: Sunfire, eluent A: water+0.1% TFA, eluent B: MeOH) to yield the desired product.
