실험 절차

To a stirred solution of NaOEt (32 g, 5 eq.) in EtOH (200 mL) was slowly added compound 282 (22 g, 1 eq.). The reaction mixture was stirred at room temperature for 30 min and diethyl malonate (11.5 mL, 0.8 eq.) was then added. The suspension was refluxed for 24 hrs. The solvent was removed under reduced pressure. The residue was suspended in H2O (200 mL) and acidified to pH 5 with 2 N aqueous HCl. The resulting solid was filtered, washed with water, and dried under reduced pressure to yield compound 283 as a brown solid in 98% yield. 1H NMR (DMSO-d6, 400 MHz) δ 5.77 (s, 1H), 8.68 (s, 1H).
