Procedure

A suspension of N-[1-{[3-(aminomethyl)phenyl]methyl}-5-fluoro-4-(methyloxy)-1H-indazol-3-yl]-5-chloro-2-thiophenesulfonamide (for a preparation see Intermediate 61) (100 mg, 0.208 mmol) in dichloromethane (0.5 mL), pyridine (0.5 mL) and potassium hydroxide (11.67 mg, 0.208 mmol) was treated with 2-chloro-1,1-dimethyl-2-oxoethyl acetate (0.054 mL, 0.37 mmol) and the mixture was stirred for 2.5 h. The reaction mixture was concentrated in vacuo and the orange residue was dissolved in 1:1 MeOH-DMSO (1 mL) and purified by Mass Directed AutoPrep on Sunfire C18 column using Acetonitrile Water with a TFA modifier (Method B). The solvent was evaporated in vacuo to give the title compound (58 mg, 49%). LCMS (System A) RT=1.04 min, ES+ve m/z 567/569 (M+H)+.
