Added to a solution of 0.230 g (0.40 mmol) of 2-(4-fluorophenyl)-6-[(3R)-3-methylpiperazin-1-yl]-3-{1-[(4-methylphenyl)sulphonyl]-1H-pyrrolo[2,3-b]pyridin-4-yl}imidazo[1,2-b]pyridazine obtained in step 3.3, in 5 ml of methanol, is 0.13 ml (0.76 mmol) of a 6N aqueous solution of sodium hydroxide. The mixture is heated at 60° C. for 30 minutes then poured into 100 ml of water. The product is extracted with dichloromethane. The organic phase is separated, dried over sodium sulphate and the solvent is removed by evaporation under reduced pressure. The residue obtained is recrystallized in acetonitrile in order to give 0.156 g of 2-(4-fluorophenyl)-6-[(3R)-3-methylpiperazin-1-yl]-3-(1H-pyrrolo[2,3-b]pyridin-4-yl)imidazo[1,2-b]pyridazine after drying.
