Procedure

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 (0.430 ml, 0.86 mmoles) was treated with 3-methoxyphenylboronic acid (75 mg, 0.491 mmol) and Pd[PPh3]4 (29 mg, 0.025 mmol) for 18 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 (58 mg, 55%). MS m/e 435.22 (M+H+)
