Procedure

A mixture of 4-chloro-N-[2-(3-hydroxy-propoxy)-6-methyl-phenyl]-N-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzamide (206 mg, 0.45 mmol), 2-bromo-5-(trifluoromethyl)-benzonitrile (75 mg, 0.3 mmol), Pd(PPh3)4 (34.7 mg, 0.03 mmol), Na2CO3 (190.8 mg, 1.8 mmol) in dioxane/water (9/1, 1.5 mL), was heated at 95° C. for approximately 16 hrs after degassing of the solvent with a stream of nitrogen. The reaction was allowed to cool to room temperature. The mixture was diluted with water and extracted with ethyl acetate. The organic layer was further washed with brine and dried with MgSO4. The filtrate was evaporated and the residue purified by preparative TLC [eluent: 40% acetone in hexane] to afford 4-chloro-3-(2-cyano-4-trifluoromethyl-phenyl)-N-[2-(3-hydroxy-propoxy)-6-methyl-phenyl]-N-methyl-benzamide 10-1 (120 mg). MS [M+H]+: 502.9; tR=8.15 min. (method 2)
