A solution of ethyl 5-bromo-l-methylpyrazole-4-carboxylate (1.0 g, 4.29 mmol), 3- nitrophenylboronic acid (859 mg, 5.15 mmol), sodium carbonate (909 mg, 8.58 mmol dissolved in 4.3 mL water), and bis(triphenylphosphine)palladium(II) dichloride (151 mg, 0.21 mmol) in DME (43 mL) was heated to 90 C overnight. After this time, General Work-up Procedure 1 was followed, and the crude residue was purified by Chromatography A to afford the title compound (710 mg, 60 % yield).<\/p>\n
