実験手順

4-i-Propyl-phenyl sulfamic acid-[6-(2-hydroxy-ethoxy)-5-(o-methoxyphenoxy)-2-(4-pyridyl)-pyrimidin-4-yl]-amide (60 mg, Example 3) was dissoved in THF (8 ml). Sodium hydride (14 mg, 60% dispersion in mineral oil) was added and stirring continued for 10 min. 5-Bromo-2-chloro-pyrimidine (37 mg) was added and the mixture was heated to 60° C. for 120 min. DMF (0.5 ml) was added and the solution was stirred at r.t. for 48 h. The solvents were evaporated, water (12 ml) and a 10% solution of citric acid was added until the pH was 3. The precipitate was filtered off and washed with water and purified by chromatography through silica gel with EtOAc/Hex=1:1 to give 4-i-propyl-phenyl sulfamic acid-[6-[2-(5-bromo-pyrimidin-2-yloxy)-ethoxy]-5-(o-methoxy-phenoxy)-2-(4-pyridyl)-pyrimidin-4-yl]-amide (55.4 mg). tR=5.30 min, (LC); [M+H]+=710.35 (ES+).
