Versuchsvorschrift

4-Chloro-5,6-diphenyl-2-(trifluoromethyl)pyrimidine (0.2 g, 0.6 mmol, prepared according to the procedure described in PCT/IB03/02879) was heated to reflux with tetra-kis triphenyl palladium (0) (0.068 g, 0.058 mmol), aqueous solution of potassium carbonate (0.16 g in 0.6 ml water), 4-(methylthio)benzene boronic acid (0.168 g, 1 mmol) and toluene (20 ml) under a nitrogen atmosphere overnight. The reaction mixture was acidified with dilute hydrochloric acid 10 ml and extracted with ethyl acetate. The organic layer was concentrated; the crude material obtained was triturated with ether and filtered to yield the title compound. 1H-NMR (DMSO-d6) δ: 2.45 (s, 3H), 7.13-7.15 (m, 4H), 7.23-7.34 (m, 8H), 7.61 (d, 2H); MS m/z: 423.1 (M++1).
