Procedure

A solution/suspension of methyl 6-hydroxy-1-naphthoate (2.49 g, 12.3 mmol), 6-methoxypyridin-3-ylboronic acid (2.26 g, 14.8 mmol), copper acetate (2.46 g, 13.6 mmol), triethylamine (6.24 g, 61.7 mmol) and 4 Å molecular sieves (2.00 g) in acetonitrile (120 mL) was stirred at RT for 16 h. The solids were filtered off. The filtrate was concentrated in vacuo. Water was added and extracted with EtOAc. The organic layer was washed with 1M aqueous NaOH solution, water, brine and dried over Na2SO4, filtered and concentrated in vacuo. Purification by silica gel chromatography afforded the title compound.
