To a stirred solution of 4-(benzyloxy)-2-hydroxybenzaldehyde (10 g, 43.9 mmol) in DMF (60 mL), was added methyl bromoacetate (48.3 mmol, 4.57 mL), and potassium carbonate (24.2 g, 175.6 mmol). The solution was heated to 80° C. and stirred for 16 h. The reaction was quenched with water (100 mL) and aqueous extraction was performed with AcOEt (2×50 mL). The organic phase was dried with sodium sulfate and concentrated. Purification was achieved via silica gel chromatography employing 0-30% AcOEt in hexane gradient. This afforded 393 as a light yellow solid (4.5 g, 37%).
