1.42 g (5 mmol) of the compound obtained in Step 1 was dissolved in 20 ml of acetonitrile, 1.38 g (10 mmol) of K2CO3 and 0.84 g (5 mmol) of 4-(2-methoxyethoxy)phenol were added thereto, which was refluxed for 15 hours. The reaction mixture was distilled under a reduced pressure to remove the solvent, and 20 ml of ethyl acetate was added thereto. The resulting mixture was washed twice with water, dried over anhydrous MgSO4, and concentrated under a reduced pressure. The concentrate was subjected to column chromatography using 20% ethyl acetate/hexane to obtain 1.76 g (yield 95%) of 1-(2-bromo-5-chlorobenzyloxy)-4-(2-methoxyethoxy)benzene.
