Dissolve trifluoromethanesulfonic acid 1-[4-(2-azepan-1-yl-ethoxy)-benzoyl]-6-methoxynaphthalen-2-yl ester (2.60 g, 6.53 mmol) in 200 ml. acetonitrile and add to this bis(pinacoloato)diboron (1.5 g, 7.96 mmol), bis(tricyclohexylphosphine)palladium (0) (0.72 g, 1.50 mmol) and cesium fluoride (7.33 g, 67.0 mmol). Heat the reaction to 100° C. until LC/MS indicates all starting material is consumed. Add to this mixture 1-bromo-2,3,5-trifluorobenzene (2.00 g, 13.06 mmol) and another 720 mg of palladium catalyst and heat at 80° C. for 24 hours. Filter the reaction, concentrate and purify on a silica gel column eluting with a 0-10% methanol/methylene chloride gradient to give 1.85 g (53%) of the title compound.
