Reaction Steps

3-{4-[4-(3,4-Difluoro-phenyl)-6-trifluoromethyl-pyrimidin-2-yl]-pyridin-2-yl}-benzenesulfonic acid tert-butylamide was prepared from 2-(2-chloro-pyridin-4-yl)-4-(3,4-difluoro-phenyl)-6-trifluoromethyl-pyrimidine (example E.104) (0.25 g, 0.67 mmol) and commercially available 3-(tert.-butylsulfamoyl)-phenylboronic acid (0.21 g, 0.82 mmol) according to the general procedure VI. Obtained as a light yellow solid (0.25 g), which was subsequently deprotected.
