Reaction Steps
To a solution of methyl 3-hydroxy-5-methoxybenzoate (Chakraporty, T. K. and Reddy, G. V. J. Org. Chem, 57, 1992, 5462.) (3.3 g, 18.1 mmol) in dry DMF (30 mL) was added K2CO3 (6.3 g, 45.3 mmol) at room temperature. The reaction was stirred at room temperature for 10 minutes then ((2-bromoethoxy)methyl)benzene (3.4 mL, 21.7 mmol) was added and the mixture stirred at 160° C. for 2 hrs. The reaction was cooled down to room temperature and diluted with EtOAc, washed with water and brine, and dried over MgSO4, filtered and concentrated to give the crude product (90%) which was used in the next step without further purification.
