To a solution of 4-i-propyl-phenyl sulfamic acid amide (642 mg; Referential Example 17) in DMF (9 ml) was added sodium hydride (250 mg). The mixture was warmed to 45° C. for 30 min. Then, 4,6-dichloro-5-(o-methoxyphenoxy)-2-(4-pyridyl)-pyrimidine (1.044 g) was added and the reaction mixture was stirred for 60 h at r.t. After acidic work up and chromatography over silicagel with Hex/EtOAc=2/5, 4-i-propyl-phenyl sulfamic acid-[6-chloro-5-(o-methoxy-phenoxy)-2-(4-pyridyl)-4-pyrimidinyl]-amide (0.42 g) can be isolated.
