الإجراء التجريبي

To a mixture of methyl 5-(benzyloxy)-2-hydroxybenzoate (10.6 g, 41.1 mmol) and K2CO3 (11.3 g, 82.2 mmol) in DMF (100 mL) was added iodomethane (2.60 mL, 49.3 mmol) drop wise over 5 minutes. The resulting mixture was stirred at room temperature overnight. The reaction mixture was poured into water (400 mL), filtered, and collected the solid. The solid was dissolved in EtOAc (300 mL), washed with water (50 mL) and brine (100 mL), dried over Na2SO4, filtered, and concentrated under reduced pressure to give methyl 5-(benzyloxy)-2-methoxybenzoate (10.4 g, 98%) as a yellow solid.
