Reaction Steps

To a partial suspension of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [1-(trans-3-hydroxy-cyclobutyl)-ethyl]-amide (85 mg, 0.16 mmol) in CH2Cl2 (3 mL) at 0° C. was added triethylamine (33 μL, 0.24 mmol) followed by methanesulfonyl chloride (14 μL, 0.18 mmol). The reaction mixture was stirred at 0° C. for 1 h then quenched with water and extracted with CH2Cl2. The organics were dried over MgSO4 and concentrated to give methanesulfonic acid trans-3-(1-{[2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carbonyl]-amino}-ethyl)-cyclobutyl ester as an off-white foam which was used without further purification.
