実験手順
To a solution of ethyl 4-cyano-3-(2,4-dichlorophenyl)-5-iodothiophene-2-carboxylate (1.26 g, 0.00279 mol) in Tetrahydrofuran (20 mL, 0.3 mol) was added water (9.2 mL, 0.51 mol) and 1M NaOH (19.5 mL, 0.0195 mol) and the solution was stirred at room temperature for 2 days. The mixture was acidified by 1M HCl (20 mL), extracted with EtOAc (3×100 mL). The organic extracts were combined, dried over Na2SO4, filtered and evaporated to afford the product (1.17 g, 99%). LCMS: (FA) ES+, 424, 426. 1H NMR (400 MHz, d1-chloroform) δ: 7.62-7.60 (m, 1H) 7.45-7.41 (m, 1H), 7.36-7.33 (m, 1H).
