Sodium Carbonate → Benzoic acid N'-[3-(4'-chloro-biphenyl-2-yl)-propionyl]-N'-isopropyl-hydrazide

Participants

Reaction Steps

A solution of benzoic acid N′-[3-(2-bromo-phenyl)-propionyl]-N′-isopropyl-hydrazide (45 mg, 0.12 mmol) in DME (4 ml)/2M Na2CO3 (225 μL, 0.45 mmol) was treated with 4-chloro-phenylboronic acid (27 mg, 0.17 mmol) and Pd[PPh3]4 (13 mg, 0.012 mmol) for 18 hours at 90° C. The reaction mixture was partitioned between water and dichloromethane. 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 solid (30 mg, 61%). LC-MS m/e 421.26 (M+H+)
