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 2-methoxycarbonylphenyl boronic acid (33 mg, 0.183 mmol) and Pd[PPh3]4 (27 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 purified first on a silica gel column with a 20-30% ethyl acetate/hexanes gradient and then by RP HPLC to afford the product as a white solid (8 mg, 14%). MS m/e 465.23 (M+H+)
