Procedure

To a solution of 4-{3-[4-(2,3-Difluoro-phenyl)-isoxazol-5-yl]-1H-pyrrolo [2,3-b]pyridin-5-yl}-cyclohex-3-enylamine (47 mg, 0.12 mmol) in DMF (2 ml) was added methanesulfonic acid benzotriazol-1-yl ester (27 mg, 0.13 mmol) and Hunig base (10 drops) and stirred for 1 h. TFA was added, and the reaction mixture was purified by HPLC to give the methanesulfonamide (25.9 mg) in 46% yield.
