To a solution of 15 g (65.5 mmol) of methyl 3-(bromomethyl)benzoate in 20 mL of anhydrous MeOH is added dropwise, at room temperature, a solution of sodium methoxide in MeOH, prepared beforehand from 2.25 g (98.2 mmol) of sodium in 65 mL of MeOH. The reaction medium is then heated for 4 hours at 65° C. and then concentrated under reduced pressure, taken up in 500 mL of DCM, washed with water (100 mL) and brine (100 mL), dried over Na2SO4, filtered and concentrated under reduced pressure. 7.8 g of methyl 3-(methoxymethyl)benzoate are obtained in the form of an oil, which is used without further purification in the following step.

1. concentrationconcentrated under reduced pressure
2. washwashed with water (100 mL) and brine (100 mL)
3. dry with materialdried over Na2SO4
4. filtrationfiltered
5. concentrationconcentrated under reduced pressure
