実験手順

A mixture of 4-tert-butyl-N-[6-{2-(6-chloropyridazin-3-yloxy)ethoxy}-5-(3-methoxyphenoxy)pyrimidin-4-yl]benzenesulfonamide (150 mg), 10% palladium-carbon (30 mg), triethylamine (52 mg), methanol (8 ml) and tetrahydrofuran (6 ml) is stirred at room temperature for five hours under hydrogen atmosphere (1 atm), and the mixture is filtered to remove the catalyst. The filtrate is concentrated to dryness under reduced pressure. The residue is treated with aqueous citric acid solution, and extracted with chloroform. The extract is washed, dried and evaporated to remove the solvent. The residue is recrystallized from ethyl acetate/diisopropyl ether to give 4-tert-butyl-N-[5-(3-methoxyphenoxy)-6-{2-(pyridazin-3-yloxy)ethoxy}pyrimidin-4-yl]benzenesulfonamide (111 mg) as crystals.
