Reaction Steps
A mixture of methyl 4-(oxoacetyl)benzoate (13.5 g, 0.0702 mol), ethyl orthoformate (29 mL, 0.18 mol), p-toluenesulfonic acid monohydrate (0.7 g) in toluene (150 mL) was refluxed for 2 h. After cooling to RT, the solvent was removed under reduced pressure. The crude material was chromatographed on silica gel to afford the desired product (15.4 g, 82%). LCMS: (M+Na)=289.0.
