실험 절차
A mixture of methyl 2-fluoro-4-(oxoacetyl)benzoate (6.0 g, 0.028 mol), ethyl orthoformate (12.0 mL, 0.071 mol), and p-toluenesulfonic acid monohydrate (200 mg) in toluene (60 mL) was heated under reflux for 4 h. After cooling, the reaction mixture was concentrated under reduced pressure to give the desired product which was used in the next step without further purification.
