Reaction Steps

To a solution of methyl 5-amino-4′-fluoro-6-hydroxybiphenyl-3-carboxylate (10.0 mg, 38.0 μmol), and isobutyric acid (2.60 mg, 29.0 μmol), and solid support triphenylphosphine (75% by weight; 40.2 mg, 0.12 mmol) in acetonitrile (0.38 mL) was added trichloroacetonitrile (7.68 μL, 77.0 μmol). The mixture was heated in a microwave reactor for 15 min at 150° C. The mixture was cooled to ambient temperature, filtered and concentrated. Purification by reverse phase HPLC (C-18, 95% water/acetonitrile→5% water/acetonitrile with 0.1% trifluoroacetic acid) gave the title compound (5 mg). LC-MS [M+1]=332.1.
