Procedure
N-tert-Butyl-4-{1-[6-(3,4-dichloro-phenyl)-4-methyl-pyrimidin-2-yl]-1H-imidazol-4-yl}-benzenesulfonamide was prepared from 4-(3,4-dichloro-phenyl)-2-(4-iodo-imidazol-1-yl)-6-methyl-pyrimidine (example E.74) (0.37 g, 0.86 mmol) and commercially available 4-(tert.-butylsulfamoyl)-phenylboronic acid (0.33 g, 1.29 mmol) according to the general procedure VI. Obtained as a light yellow solid (0.2 g) which was subsequently deprotected.
