To a solution of methyl 4-(1-bromo-6-methoxynaphthalen-2-yl)benzoate (300 mg, 0.811 mmol) (see Example 12 step 1) in DMF (10 mL) was added Zn(CN)2 (191 mg, 1.62 mmol) and Pd(PPh3)4 (93.8 mg, 0.0811 mmol). The resulting mixture was stirred at 120° C. under N2 atmosphere for 16 hours. After cooling to room temperature, the mixture was filtered and the filtrate was diluted with EtOAc (60 mL), washed with H2O (20 mL×3) and brine (20 mL), dried over anhydrous Na2SO4, filtered and concentrated in vacuo. Purification by silica gel column (PE/EtOAc=200/1 to 50/1) gave the product (210 mg, yield 82%) as a solid.
