Reaction Steps
300 mg (0.53 mmol) of 2,5-difluoro-N-(3-{1-(4-methoxybenzyl)-4-[2-(methylamino)-pyridin-4-yl]-1H-pyrazol-3-yl}phenyl)benzenesulfonamide were dissolved in 10 ml of trifluoroacetic acid and the mixture heated at 70° C. under stirring for 4 hours. The solvent was then removed in vacuo, the residue partitioned between dichloromethane and a saturated aqueous solution of sodium hydrogenocarbonate. The organic layer was dried over sodium sulphate and evaporated to dryness. The crude was finally purified by flash-chromatography on a silica gel column (CH2Cl2-CH3COCH3; from 9/1 to 8/2), giving 47 mg (20%) of the title compound.
