Reaction Steps

A mixture of [6-bromo-4-(5-ethanesulfonyl-pyridin-2-yloxy)-naphthalen-2-yl]-acetic acid methyl ester (29 mg, 0.07 mmol, methyl ester of example 12-1), zinc cyanide (10 mg, 0.084 mmol), tetrakis(triphenylphosphine)palladium(0) (18 mg, 0.014 mmol) and N,N-dimethylacetamide (0.2 mL) was stirred at 150° C. for 24 hours under an argon atmosphere. The reaction mixture was diluted with water (5 mL), and extracted with ethyl acetate (20 mL×2). The combined organic layers were washed with brine (20 mL), dried over sodium sulfate and concentrated in vacuo. The residue was purified by preparative TLC (30% ethyl acetate in petroleum ether) to give [6-cyano-4-(5-ethanesulfonyl-pyridin-2-yloxy)-naphthalen-2-yl]-acetic acid methyl ester (17 mg) as a white solid.
