Reaction Steps

5-{4-[4-Difluoromethyl-6-(6-trifluoromethyl-pyridin-3-yl)-pyrimidin-2-yl]-pyridin-2-yl}-thiophene-2-sulfonic-acid tert-butylamide was prepared from 2-(2-chloro-pyridin-4-yl)-4-difluoromethyl-6-(6-trifluoromethyl-pyridin-3-yl)-pyrimidine (example B.7) (0.39 g, 1.0 mmol) and N-tert-butyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-thiophene-2-sulfonamide (example C.1) (0.414 g, 1.2 mmol) according to the general procedure III. Obtained as an off-white solid (0.36 g), which was subsequently deprotected.
