Reaction Steps

3′-[4-(4-Chloro-phenyl)-6-methyl-pyrimidin-2-yl]-biphenyl-3-sulfonic acid tert-butylamide was prepared from 2-(3-bromo-phenyl)-4-(4-chloro-phenyl)-6-methyl-pyrimidine (example E.44) (0.11 g, 0.3 mmol) and commercially available 3-(tert.-butylsulfamoyl)-phenylboronic acid (0.09 g, 0.35 mmol) according to the general procedure VI. Obtained as a light brown solid (0.16 g), which was subsequently deprotected.
