Procedure
The furyl bromide (16) (100 mg, 0.30 mmol) was coupled to 3,5-difluoro-phenylboronic acid (48 mg, 0.30 mmol) using Method E. During this reaction, hydrolysis occurred. The residue was extracted using Work-up E1 to give the acid. The residue was purified by column chromatography eluting with 20% heptane:75% EtOAc:5% AcOH to give the title compound.
