실험 절차

Diethyl 2-((2-fluoro-4-iodophenylamino)methylene)malonate (Intermediate 10, 13.45 g, 33.05 mmol) was placed in a 250 mL round bottom flask with Eaton's Reagent (55 mL, 0.29 mol) and aged while stirring at 90° C. for 4-5 days. The reaction was then cooled to 5° C. and was slowly quenched with saturated sodium carbonate solution (500 ml) at 10° C. to form a clumpy brownish-yellow solid. The precipitate was vacuum filtered and washed with water (300 ml). The collected solid was dried under vacuum at 50° C. for 16 h, resulting in 10.7 g (90%) of light tan solid.
