Reaction Steps

A mixture of 2,4-difluoro-4′-(3-nitro-benzyloxy)-biphenyl (28 mg, 0.082 mmol), succinic anhydride (8.2 mg, 0.083 mmol) and 10% Pd/C (4.4 mg) in THF (3 mL) was hydrogenated at 45 psi for 4 hrs. The reaction mixture was filtered and evaporated. The crude product was purified by flash chromatography with a 0-50% gradient of ethyl acetate in hexanes to yield 7 mg (20.7%) of N-[3-(2′,4′-difluoro-biphenyl-4-yloxymethyl)-phenyl]-succinamic acid as a solid. LC-MS (ES) calculated for C23H19F2NO4, 411.41; found m/z 410.2 [M−H]−.
