Procedure

1,1-Dimethylethyl[(3-{[3-{bis[(5-chloro-2-thienyl)sulfonyl]amino}-4-(hydroxymethyl)-1H-indazol-1-yl]methyl}phenyl)methyl]carbamate (for a preparation see Intermediate 71) (93 mg, 0.125 mmol) was dissolved in dichloromethane (0.5 mL), trifluoroacetic acid (0.125 mL) was added to the solution and stirred for 1 h under nitrogen. The reaction mixture was concentrated under a stream of nitrogen and the residue was dissolved in methanol and loaded onto a methanol pre-conditioned sulphonic acid (SCX-2) cartridge (10 g). The cartridge was washed well with methanol, followed by 2M ammonia in methanol. Evaporation of the solvent from the ammoniacal fractions gave the title compound (53 mg, 66%) as a white solid. LCMS (System A) RT=0.89 min, ES+ve m/z 643/645 (M+H)+.
