Reaction Steps

##STR152## (1) A solution of N-[6-(2-benzyloxyethoxy)-5-(4-methylphenyl)-2-methylsulfonylpyrimidin-4-yl]-4-tert-butylbenzenesulfonamide obtained in Reference Example 11-(6) (300 mg) in 2-aminoethanol (4 ml) is heated with stirring at 120° C. for three hours. After cooling, to the reaction solution is added an aqueous ammonium chloride solution, and the mixture is extracted with ethyl acetate. The ethyl acetate layer is washed with water, dried, and evaporated under reduced pressure to remove the solvent. The residue is purified by silica gel column chromatography (solvent; chloroform:methanol=10:1), and recrystallized from isopropyl ether-n-hexane to give N-[6-{2-benzyloxyethoxy)-2-(2-hydroxyethylamino)-5-(4-methylphenyl)pyrimidin-4-yl]-4-tert-butylbenzenesulfonamide (260 mg) as a crystal.
