Reaction Steps

Cesium carbonate (45 mg, 0.137 mmol) and thiophenol (24 ml, 0.229 mmol) were added to a solution of 4-methoxy-1H-indazol-5-yl 2-nitrobenzenesulfonate (40 mg, 0.115 mmol) in N,N-dimethylformamide (1 ml) at 0° C. After 30 minutes, the reaction solution was poured into water (20 ml) and extracted with ethyl acetate (20 ml×2). The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure, and the resulting residue was purified by a silica gel column chromatography (eluent: hexane/ethyl acetate) to obtain 4-methoxy-1H-indazol-5-ol (19 mg, 100%).
