Reaction Steps

Benzylsulfamic acid [6-(2-hydroxy-ethoxy)-2-methanesulfonyl-5-(2-methoxy-phenoxy)-pyrimidin-4-yl]-amide (85 mg) were dissolved in THF (2 ml) and morpholine (2 ml) was added. The reaction mixture was stirred at 45° C. for 48 hours, poured onto water, acidified with solid citric acid and extracted with EtOAc (2×). The combined EtOAc layers were washed with 10% citric acid solution and with brine, dried over magnesium sulfate, filtered and the solvent was evaporated. The crude product was purified by chromatography on plates with toluene/EtOAc=1/1 to give benzylsulfamic acid [6-(2-hydroxy-ethoxy)-5-(2-methoxy-phenoxy)-2-morpholin-4-yl-pyrimidin-4-yl]-amide (Example 205) (60 mg). LC-MS: tR=4.69; [M+H]+=532.15.
