Reaction Steps

(3,5-dihydroxy-phenyl)-acetic acid methyl ester (5 g, 27.4 mmol) in anhydrous DMF (20 mL) was treated with K2CO3 (11.4 g, 82.5 mmol) and benzyl bromide (6.5 mL, 55 mmol). The resultant mixture was stirred overnight at room temperature. Water was added to the reaction mixture and the aqueous layer extracted with EtOAc (3×50 mL). The organic layers were combined, washed with brine, dried over MgSO4, filtered and concentrated to give the title compound as a brown solid (9.82 g, 99%).
