실험 절차
A solution of methyl 6-chloro-5-(phenylethynyl)-1H-indazole-3-carboxylate (20 mg, 0.064 mmol) in methanol (1 mL) was treated with 10N aqueous sodium hydroxide (2 drops) and stirred at room temperature for 16 hours. The reaction mixture was then treated with additional 10N aqueous sodium hydroxide (2 drops) and heated to 70° C. for two hours. The cooled reaction mixture was evaporated in vacuo, and treated with 1N citric acid. The resulting solids were collected by filtration, dried and purified using prep-HPLC to afford the title compound (1 mg). MS (ES+) 374.9 (M+DMSO)+. Retention time: 1.8 min; Xbridge C18 5 μm 4.6×50 mm, 95% H2O/5% MeCN linear to 5% H2O/95% MeCN over 4.0 min, HOLD at 5% H2O/95% MeCN to 5.0 min. (0.03% NH4OH). Flow: 2.0 mL/min.
