Dimethylformamide → Ethyl 3-(4-(3-iodobenzyloxy)phenyl)-3-(4-fluorophenyl)propanoate

Participants

Reaction Steps

Cs2CO3 (4.89 g 15 mmol) and 1-(bromomethyl)-3-iodobenzene (4.45 g, 15 mmol) were added successively to a dry DMF (20 mL) solution of 45.2 (2.88 g, 10 mmol). The reaction mixture was stirred at room temperature overnight, diluted with ethyl acetate (200 mL), washed with water (100 mL×2) and brine (100 mL), and dried over Na2SO4. The solvent was removed under vacuum and the residue was purified by flash chromatography to give compound 47.1 as a colorless oil. MS ESI (pos.) m/e: 505.0 (1+H).
