実験手順

Combine Pd(OAc)2 (46 mg, 0.20 mmol), tricyclohexylphosphine (95 mg, 0.34 mmol), and CsF (1.85 g, 12.26 mmol) in CH3CN (20 mL) under N2. Stir the reaction mixture for 5 minutes. Add acetic acid 5-[4-(2-piperidin-1-yl-ethoxy)-phenoxy]-6-trifluoromethanesulfonyloxy-naphthalen-2-yl ester (730 mg, 1.36 mmol) and bis(neopentyl glycolato)diboron (460 mg, 2.04 mmol) to the reaction mixture. Heat to 90° C. and stir for about 5 minutes. Add trifluoro-methanesulfonic acid 4-methanesulfonyl-3-methoxy-phenyl ester (500 mg, 1.5 mmol) and continue to heat the mixture for two hours. Cool to room temperature, add water (100 mL), and extract the aqueous layer with CH2Cl2 (3×100 mL). Combine the organic layers and dry with Na2SO4, filter and concentrate. Purify by flash column chromatography (silica gel, 0 to 5% MeOH/CH2Cl2) to give 260 mg of the title compound (33%): mass spectrum: (ion spray): m/z=590.4 (M+H).
