Procedure
3′-[4-(3,4-Dichloro-phenyl)-6-methyl-pyrimidin-2-yl]-biphenyl-3-sulfonic acid tert-butylamide was prepared from 2-(3-bromo-phenyl)-4-(3,4-dichloro-phenyl)-6-methyl-pyrimidine (example E.62) (0.39 g, 1.0 mmol) and commercially available 3-(tert.-butylsulfamoyl)-phenylboronic acid (0.31 g, 1.2 mmol) according to the general procedure VI. Obtained as a light brown solid (0.54 g), which was subsequently deprotected.
