Versuchsvorschrift

To a mixture of methanol (1 ml) and THF (2 ml) was added sodium hydride (100 mg, 60% dispersion in mineral oil) followed by the addition of 4-i-propyl-phenyl sulfamic acid-[6-chloro-5-(o-methoxyphenoxy)-2-(4-pyridyl)-pyrimidin-4-yl]-amide (100 mg, Referential Example 1e)). DMF (0.5 ml) was added and the reaction mixture was heated to 80° C. for 20 h. The solvents were evaporated, water (14 ml) and a 10% solution of citric acid was added until the pH was 3. The precipitate was filtered off and washed with water to give 4-i-propyl-phenyl sulfamic acid-[6-methoxy-5-(o-methoxyphenoxy)-2-(4-pyridyl)-pyrimidin-4-yl]-amide (100 mg). tR=5.08 min, (LC); [M+H]+=522.45 (ES+).
