Procedure

To a solution of N-(2-(methyloxy)-5-{1-(phenylsulfonyl)-4-[5-(tetrahydro-1,4-oxazepin-4(5H)-ylmethyl)-1,3,4-oxadiazol-2-yl]-1H-indazol-6-yl}-3-pyridinyl)methanesulfonamide (50 mg, 0.078 mmol) in 1,4-dioxane (1 ml) was added 2M sodium hydroxide (1 ml, 2.000 mmol) and the mixture stirred at 20° C. for 2 h. The mixture was partitioned between ethyl acetate (5 ml) and saturated ammonium chloride solution (2 ml), separating the layers with a hydrophilic frit. The organic layer was evaporated to dryness under a stream of nitrogen to give the title compound as a pale brown solid (35 mg).
