Versuchsvorschrift

In a 25 mL 3-neck RBF equipped with N2-bubbler and thermo-pocket, N-(3-((5-fluoro-2-((4-(2-methoxyethoxy)phenyl)amino)pyrimidin-4-yl)amino)phenyl)-2,3-dihydroxypropanamide (I-4) (0.08 g) was dissolved in THF (5 mL), TEA (0.0212 g) was added at room temperature. The reaction mixture was cooled to 0° C. Methane sulphonyl chloride (0.021 g) was slowly added at 0° C. The reaction mixture was stirred at room temperature for 1 h. The reaction was monitored on TLC by using ethyl acetate (100%) as mobile phase. (Only 50% of the reaction was complete on TLC). The reaction was diluted with ethyl acetate (20 mL), washed with saturated NaHCO3 (25 mL). The organic layer was separated and dried over sodium sulfate. Ethyl acetate was removed under reduced pressure at 40° C. Crude material was purified by Combiflash chromatography eluted with 7% ethyl acetate in hexane. The solvent was removed under vacuum to give 0.03 g of 3-((3-((5-fluoro-2-((4-(2-methoxyethoxy)phenyl)amino)pyrimidin-4-yl)amino)phenyl)amino)-2-hydroxy-3-oxopropyl methanesulfonate.
