反応手順
A mixture of ethyl 3-oxo-3-phenylpropanoate (17.2 mL, 100 mmol), triethyl orthoformate (24.5 mL, 150 mmol), and acetic anhydride (38 mL, 400 mmol) was stirred at 135° C. for 5 hr. Distillation under reduced pressure gave ethyl 2-benzoyl-3-ethoxyacrylate (14.7 g, 59 mmol, 59% yield) as a yellow liquid.
