Procedure

Charge a flask with trifluoromethanesulfonic acid 6-methoxy-1-[4-(2-piperidin-1-yl-ethoxy)-benzoyl]-naphthalen-2-yl ester (2.13 g, 4.0 mmol), 2,3,4-trifluorophenyl boronic acid (1.0 g, 5.7 mmol), trans-dichlorobis(triphenylphosphine)palladium II, (561 mg, 0.8 mmol) and cesium fluoride (5.5 g, 36 mmol) and add 50 mL of acetonitrile. Heat the mixture at 80° C. for 4 hours. Cool and filter the mixture and purify on an SOX column, eluting with 2N ammonia/ethanol. Purify further on a silica column eluting with 2% 2N ammonia/methanol/methylene chloride to give 880 mg (43%) of the title compound: 1H-NMR (CD3OD, 400 MHz) δ 7.93 (d, J=8.8 Hz, 1H); 7.50 (d, J=8.4 Hz, 3H); 7.39 (d, J=8.8 Hz, 1H); 7.35 (d, J=2.4 Hz, 1H); 7.07 (dd, J=9.2, 2.8 Hz, 1H); 6.96-6.87 (m, 2H); 6.80 (d, J=9.6 Hz, 2H); 4.10-4.07 (t, 2H); 3.91 (s, 3H); 2.72-2.69 (t, 2H); 2.48-2.48 (m, 4H); 1.61-1.55 (m, 4H); 1.46-1.43 (m, 2H).
