Procedure

A solution of 1-[3-fluoro-4-(methylsulfonyl)phenyl]-5-[4-(2-furyl)phenyl]-1H-pyrazole-3-carboxylic acid (0.2 g, 0.469 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (WSC, 0.108 g, 0.563 mmol), and morpholine (0.04 mL, 0.492 mmol) in methylene chloride (10 mL) was stirred at room temperature for 3.5 hours. The mixture was diluted with methylene chloride (20 mL) and washed with saturated NaHCO3, water, and brine, dried over MgSO4, filtered, and concentrated in vacuo. The crude mixture was purified by flash chromatography eluting with methylene chloride/methanol (30/1). The resulting solid was recrystallized from methylene chloride-hexane to give the title compound to give the title compound (0.1 g, 43.1% yield).
