Reaction Steps

3′-[4-Trifluoromethyl-6-(6-trifluoromethyl-pyridin-3-yl)-pyrimidin-2-yl]-biphenyl-3-sulfonic acid tert-butylamide was prepared from 2-(3-bromo-phenyl)-4-trifluoromethyl-6-(6-trifluoromethyl-pyridin-3-yl)-pyrimidine (example B.2) (0.448 g, 1.0 mmol) and commercially available 3-(tert.-butylsulfamoyl)-phenylboronic acid (0.31 g, 1.2 mmol) according to the general procedure III. Obtained as light yellow solid (0.56 g), which was subsequently deprotected.
