A solution of 4-benzyloxy-2-fluoro benzaldehyde (Compound 8, 16 g, 69.6 mmol) in methanol (100 mL) and dichloromethane (100 mL) was treated with sodium borohydride (5.26 g, 139 mmol). After 2 h at ambient temperature, the volatiles were evaporated in vacuo, the residue was diluted with water and dilute aqueous hydrochloric acid and extracted with diethyl ether (×2). The combined organic phase was dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford the title product as a white solid (15 g, 95%).
