Reaction Steps

N-tert-Butyl-3-{1-[4-(5-chloro-thiophen-2-yl)-6-trifluoromethyl-pyrimidin-2-yl]-1H-imidazol-4-yl}-benzenesulfonamide was prepared from 4-(5-chloro-thiophen-2-yl)-2-(4-iodo-imidazol-1-yl)-6-trifluoromethyl-pyrimidine (example B.1) (0.46 g, 1.0 mmol) and commercially available 3-(tert.-butylsulfamoyl)-phenylboronic acid (0.28 g, 1.1 mmol) according to the general procedure III. Obtained as a light yellow solid (0.3 g) which was subsequently deprotected.
