Methyl 1-(4-(bromomethyl)phenyl)cyclopropanecarboxylate (2.478 g, 9.207 mmol) was added to a mixture of 3-hydroxybenzophenone (2.19 g, 11.05 mmol) and potassium carbonate (3.054 g, 22.10 mmol) in dimethyl formamide (46 mL). The reaction mixture was stirred at 60° C. for 16 hours. The reaction mixture was diluted with water and extracted with ethyl acetate (×3). The combined organic extracts were washed with 10% aqueous potassium carbonate (×5), 2M NaOH (×5), brine and dried (magnesium sulfate), filtered, and concentrated under reduced pressure to afford the title compound (3.721 g, quantitative yield). The material was used directly in the next step with no further purification.
