Reaction Steps

3′-[4-(5-Chloro-thiophen-2-yl)-6-trifluoromethyl-pyrimidin-2-yl]-biphenyl-3-sulfonic acid tert-butylamide was prepared from 2-(3-bromo-phenyl)-4-(5-chloro-thiophen-2-yl)-6-trifluoromethyl-pyrimidine (example B.3) (0.42 g, 1.0 mmol) and commercially available 3-(tert.-butylsulfamoyl)-phenylboronic acid (0.334 g, 1.3 mmol) according to the general procedure III. Obtained as an off-white solid (0.22 g), which was subsequently deprotected.
