実験手順

The tert-butyl 9-{2-(4-fluorophenyl)-3-[1-(4-methylphenylsulphonyl)-1H-pyrrolo[2,3-b]pyridin-4-yl]imidazo[1,2-b]pyridazin-6-yl}-2,9-diazaspiro[5.5]undecane-2-carboxylate obtained in step 5.1 is dissolved in 3 ml of a mixture of methanol and tetrahydrofuran (2/1) and is treated using 0.09 ml (0.54 mmol) of a 6N aqueous solution of sodium hydroxide at 60° C. for 1 and a half hours. The solvent is evaporated under reduced pressure and the residue taken up in 3 ml of water. The product is extracted 2 times with 3 ml of dichloromethane. The organic phase is dried over sodium sulphate and the solvent is removed by evaporation under reduced pressure. The residue obtained is then purified by chromatography on a silica gel column (4 g) by eluting with a gradient of dichloromethane, methanol and aqueous ammonia (of 95/5/05 to 90/10/1) in order to give 0.06 g of tert-butyl 9-[2-(4-fluorophenyl)-3-(1H-pyrrolo[2,3-b]pyridin-4-yl)imidazo[1,2-b]pyridazin-6-yl]-2,9-diazaspiro[5.5]undecane-2-carboxylate after crystallization in 10 ml of acetonitrile, filtration and drying.
