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

Participants

Reaction Steps

A solution of benzoic acid N′-[2-(2-bromo-phenylsulfanyl)-acetyl]-N′-isopropyl-hydrazide (100 mg, 0.246 mmol) in DME (5 ml)/2M Na2CO3 (0.43 ml, 0.86 mmoles) was treated with 2-fluorophenylboronic acid (69 mg, 0.49 mmol) and Pd[PPh3]4 (28 mg, 0.025 mmol) for 12 hours at 90° C. The reaction mixture was partitioned between water and DCM. The organic layer was washed with brine, dried over sodium sulfate, filtered, and concentrated. The crude was adsorbed on silica and purified on a silica gel column with a 20-50% ethyl acetate/hexane gradient to afford the product as a solid (72 mg, 68%). MS m/e 423.22 (M+H+)
