Procedure

To sodium hydride (27 mg, 60% in mineral oil) was added THF (15 ml) followed by 2-phenyl-ethanesulfonic acid [6-(2-hydroxy-ethoxy)-5-p-tolyl-pyrimidin-4-yl]-amide (80 mg, Referential Example 1). The mixture was stirred for 1 h at rt before 2-chloro-5-trifluoromethyl-pyridine (86 mg) was added. Stirring was continued for 17 h at 80° C. The solvent was evaporated, the residue was dissolved in water (20 ml), acidified with citric acid. The suspension was treated with hexane (15 ml). The solid material was collected, washed with hexane:EA 1:1 (20 ml) and dried to yield 2-phenyl-ethanesulfonic acid {5-p-tolyl-6-[2-(5-trifluoromethyl-pyridin-2-yloxy)-ethoxy]-pyrimidin-4-yl}-amide (96 mg) as beige powder. LC-MS: tR=5.86 min, [M+1]+=559.20, [M−1]−=557.37.
