Reaction Steps

N-tert-Butyl-3-{1-[6-(4-chloro-phenyl)-4-trifluoromethyl-pyrimidin-2-yl]-1H-imidazol-4-yl}-benzenesulfonamide was prepared from 4-(4-chloro-phenyl)-2-(4-iodo-imidazol-1-yl)-6-trifluoromethyl-pyrimidine (example E.70) (0.68 g, 1.5 mmol) and commercially available 3-(tert.-butylsulfamoyl)-phenylboronic acid (0.46 g, 1.8 mmol) according to the general procedure VI. Obtained as a light yellow solid (0.34 g) which was subsequently deprotected.
