Dissolve trifluoromethanesulfonic acid 6-methoxy-1-[4-(2-piperidin-1-yl-ethoxy)-benzyl]-naphthalen-2-yl ester (1.00 g, 1.91 mmol) in 20 mL of degassed acetonitrile and add 2,4-difluorophenyl boronic acid (0.60 g, 3.82 mmol), trans[dichlorobis(triphenylphosphine)]palladium II (0.27 g, 0.38 mmol) and sonicate briefly. Next add cesium fluoride (2.61 g, 17.19 mmol) and heat to 75° C. for one hour. Add Celite and filter. Concentrate the solvent under vacuum, dissolve in methanol and purify on an SCX cartridge, eluting with 2N ammonia/methanol to isolate the title compound.
