実験手順

Dissolve 3-(5-cyano-3′-trifluoromethyl-[2,2′]bipyridinyl-6-yl)-2-oxo-propionic acid ethyl ester (70 mg, 0.193 mmol) and 4-trifluoromethyl aniline (31 mg, 0.193 mmol) in AcOH (1 mL). Heat the mixture at 100° C. for 1.5 hours. Cool the mixture in ice and add H2O (5 mL). Extract three times with EtOAC (3×10 mL). Combine the organic extracts and wash with 1 N NaOH (30 mL) and brine (30 mL). Dry the organic extract over Na2SO4 and remove the solvent under reduced pressure. Purify the crude product using silica gel chromatography eluting with hexane/acetone (3:1) to yield the title compound. MS 507.15 (M+1)
