Reaction Steps

To a solution of 1-(2-bromo-4-methoxyphenyl)ethanone (6.2 g, 27.06 mmol) obtained in Step 1 in EtOH (50 mL) at 0° C. was added sequentially aq. NaOH solution (8.12 mL, 81.19 mmol, 3 eq) and benzaldehyde (3.3 mL, 32.48 mmol, 1.2 eq). After being stirred for additional 4 h at room temperature, the mixture was diluted with H2O and neutralized with 3N HCl. The resulting mixture was extracted with EtOAc (20 mL×3). The extracts were washed with brine, dried over MgSO4, and concentrated in vacuo to obtain the desired product (6 g, 70%).
