Sodium Carbonate → benzoic acid N'-[2-(5-fluoro-biphenyl-2-yloxy)-acetyl]-N'-isopropyl-hydrazide

Participants

Reaction Steps

A solution of benzoic acid N′-[2-(2-bromo-4-fluoro-phenoxy)-acetyl]-N′-isopropyl-hydrazide (50 mg, 0.122 mmol) in DME (3 ml)/2M Na2CO3 (0.215 ml, 0.427 mmol) was treated with phenylboronic acid (22 mg, 0.183 mmol) and Pd[PPh3]4 (28 mg, 0.0244 mmol) for 12 hours at 90° C. The reaction mixture was partitioned between water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, filtered, and concentrated. The crude was absorbed on silica and purified on a silica gel column with a 30-50% ethyl acetate/hexanes gradient to afford the product as a white solid (44 mg, 89%). MS m/e 407.22 (M+H+)
