Reaction Steps

MeOH (0.3 mL, 7.4 mmol) was added to the product from step 1 (0.962 g, 4.6 mmol), Ph3P (1.79 g, 6.8 mmol), and dichloromethane (10 mL). Then DEAD (1.32 mL, 8.4 mmol) was added to the reaction. Reaction was stirred at room temperature for 4 days. Reaction solution was concentrated by rotary evaporation and the resulting residue was purified with silica gel prep plates and 1:3 EtOAc/Hexane as eluent. Obtained 1.10 g of 4-Acetoxy-2-methoxy-benzoic acid methyl ester in quantitative yield.
