実験手順

A solution of methyl 6-{[(trifluoromethyl)sulfonyl]oxy}-1-naphthoate (271 g, 0.81 mol) (from multiple batches), tetrakis(triphenylphospine)palladium (0) (37.4 g, 0.032 mol), 2 M sodium carbonate solution (1.3 L) and 4-hydroxyphenyl boronic acid (134 g, 0.97 mol) in ethylene glycol dimethyl ether (1.5 L) was heated at 80° C. for 1.5 h. The reaction mixture was cooled to room temperature and diluted with ethyl acetate (2 L) and water (2 L). The ethyl acetate layer was dried over anhydrous sodium sulfate, filtered and concentrated to a dark semisolid residue. The crude material was purified by crystallization from dichloromethane-heptane to give 199 g of the product as a tan solid.
