ethyl (E)-4-cyano-3-phenylbut-3-enoate

反応条件: temp:160.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 4-Cyano-3-phenyl-but-3-enoic acid ethyl ester (crude, 9.37 g, 0.043 mol), ethylenediamine (3 mL, 0.043 mol) were mixed in dichlorobenze (20 mL) and heated at 160° C. overnight. The resulting suspension was cooled to room temperature, filtered, and the filtrated cake was washed with EtOAc and finally dried to provide the title compound as a brownish yellow solid. MS m/e 213 (M+H)+. The resulting suspension was cooled to room temperature filtered the filtrated cake was washed with EtOAc finally dried
