실험 절차
A mixture of 2,2-dimethyl-5-[({4-[3-(methyloxy)phenyl]-2-thienyl}amino)methylidene]-1,3-dioxane-4,6-dione (Description 41) (1.2 g, 3.34 mmol) and diphenyl ether (15 mL, 94 mmol) was heated at 220° C. for 1 h. After cooling to RT, the mixture was purified by chromatography on silica, eluting with a gradient of 0-100% ethyl acetate in DCM, to give the title compound (487 mg). LCMS (A) m/z: 258 [M+1]+, Rt 0.93 min (acidic).
