Reaction Steps

To 1.5 g (4.8 mmol) of product from Step 1 in 12.5 mL of toluene at room temperature was added 0.28 g (0.24 mmol, 0.05 eq.) of Pd(PPh3)4. After stirring for 5 min, 1.1 g (5.7 mmol, 1.2 eq.) of 4-fluorophenylboronic acid in 5.5 mL of EtOH followed by 11.5 mL of 2 M aqueous Na2CO3 were added. After heating at 90° C. for 12 h the reaction was judged complete, cooled and diluted with Et2O (100 mL) and water (50 mL). The resulting layers were separated and the aqueous layer extracted twice with Et2O (100 mL). The combined organic layers are dried over MgSO41 filtered and concentrated under reduced pressure. The resulting residue was purified by column chromatography to yield the desired methyl 4-ethyl-4′-fluoro-1,1′-biphenyl-2-carboxylate. C16H15O2F+H+ requires 258 found 258.
