Versuchsvorschrift

To a suspension of 2-(6-chloro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-azetidin-3-yl-ethyl)-amide hydrochloride (65 mg, 0.11 mmol) in CH2Cl2 (2 mL) at 0° C. was added triethylamine (47 μL, 0.33 mmol) followed by methanesulfonyl chloride (10 μL, 0.12 mmol). The reaction mixture was stirred at 0° C. for 30 min then at room temperature for 1 h. The reaction was quenched with water and extracted with CH2Cl2. The combined organics were dried over MgSO4 and concentrated. The residue was purified by silica gel chromatography with 0% to 5% MeOH/CH2Cl2 (0.5% NH4OH) to afford 35 mg (50%) of 2-(6-chloro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [1-(1-methanesulfonyl-azetidin-3-yl)-ethyl]-amide as a pale yellow solid.
