실험 절차
To a suspension of 462 mg of cyclohexanecarboxylic acid (1-benzyl-3-methyl-5-phenyl-1H-pyrazol-4-yl)-amide thiophene-2-carboxylic acid (3-methyl-5-phenyl-1H-pyrazol-4-yl)-amide in 5.6 mL of phosphorous oxychloride was added 2.57 g of phosphorous pentoxide and the resulting suspension was heated at 120° C. for 5 h. The reaction mixture was cooled to rt and quenched with the addition of ice and water and then neutralized with solid sodium carbonate. The aqueous mixture was extracted with ethyl acetate and the combined organic extracts were washed with brine, dried (magnesium sulfate) and concentrated under reduced pressure. The residue was purified by means of MPLC (12 g SiO2, 40% EtOAc:Heptane) to give the title compound as a tan solid.
