Conditions

Temperature: 100 °C

Procedure

Dissolve trifluoromethanesulfonic acid 1-[4-(2-azepan-1-yl-ethoxy)-benzoyl]-6-methoxynaphthalen-2-yl ester (990 mg, 1.8 mmol), 2,4,6-trifluorophenylboronic acid (634 mg, 3.6 mmol), potassium phosphate (2.2 g, 10.8 mmol), tetrakis(triphenylphosphine)palladium (416 rag, 0.4 mmol) in dry DMF (25 mL) and heat at 100° C. for 3 hours. Purify reaction by SCX column. Additional purification is done by silica get chromatography using a 1-3% gradient of methanol in dichloromethane to yield 320 mg (35%) of the title compound: mass spectrum (ion spray) m/z=534 (M+H).
