Sodium Carbonate → thiophene-3-carboxylic acid N'-[2-(5-fluoro-2'-trifluoromethoxy-biphenyl-2-yloxy)-acetyl]-N'-isopropyl hydrazide

Participants

Reaction Steps

A solution of thiophene-3-carboxylic acid N′-[2-(2-bromo-4-fluoro-phenoxy)-acetyl]-N′-isopropyl-hydrazide (251 mg, 0.60 mmol) in DME (5 ml)/2M Na2CO3 (1.05 ml, 2.12 mmol) was with 2-trifluoromethoxyphenylboronic acid (187 mg, 0.91 mmol) and Pd[PPh3]4 (140 mg, 0.12 mmol) in a microwave oven at 150° C. for 10 min. 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 30-50% ethyl acetate/hexane gradient to afford the product as a solid (188 mg, 63%). MS m/e 497.41 (M+H+)
