実験手順

To a solution of ethyl 4-cyano-3-(2,4-dichlorophenyl)-5-iodothiophene-2-carboxylate (1.44 g, 0.00318 mol) in tetrahydrofuran (20 mL) and water (10 mL) was added a solution of 1.00M sodium hydroxide in water (16 mL). The solution was allowed to stir overnight. The reaction was quenched with a solution of 1N HCl (18 mL) and extracted with ethyl acetate. The organic extracts were washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to afford the crude title compound (1.50 g, 100%) used directly in the next reaction. LCMS: (FA) ES−, 422. 1H NMR (400 MHz, d6-DMSO) δ: 7.68 (d, 1H, J=2.0 Hz), 7.46-7.34 (m, 2H).
