Reaction Steps

A solution of methyl 6-chloro-5-(phenylethynyl)-1H-indazole-3-carboxylate (20 mg, 0.064 mmol) in methanol (1 mL) was treated with 10 N aqueous sodium hydroxide (2 drops) and stirred at room temperature for 16 hours. The reaction mixture was then treated with additional 10 N aqueous sodium hydroxide (2 drops) and heated to 70° C. for two hours. The cooled reaction mixture was evaporated in vacuo, and treated with 1 N 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.
