Procedure

Sodium borohydride (3.09 mg, 0.082 mmol) was added to a stirring solution of N-({3-[(4-acetyl-3-{[(5-chloro-2-thienyl)sulfonyl]amino}-1H-indazol-1-yl)methyl]phenyl}methyl)acetamide (for a preparation see Intermediate 75) (40 mg, 0.068 mmol) in MeOH (2 mL) at 25° C. under nitrogen. The reaction mixture was stirred at room temp. for 2 hours, and then 1N HCl (5 mL) was slowly added and the methanol was evaporated in vacuo. The product was extracted with EtOAc (2×20 mL) and the combined organic layers were dried by passing through a hydrophobic frit and concentrated. The residue was dissolved in DMSO (1 mL) and purified by Mass Directed AutoPrep on Sunfire C18 column using Acetonitrile Water with a Formic acid modifier (Method A). The solvent was evaporated in vacuo to give the title compound (18 mg, 48%). LCMS (System A) RT=0.97 min, ES+ve m/z 519/521 (M+H)+.
