Combine 3,3,3-trifluoropropyl tosylate (4.057 gm; 15.12 mmol), 3-hydroxybenzaldehyde (1.85 gm; 15.12 mmol), and K2CO3 (4.15 gm; 30.0 mmol) in DMF (80 mL) and heat at 100° C. After 18 hours, cool to room temperature, dilute with water (200 mL) and extract with dichloromethane (2×200 mL). Combine organic extracts and wash sequentially with water (100 mL), 0.1 M NaOH (2×100 mL), saturated sodium bicarbonate (100 mL) and saturated brine (100 mL), dry (MgSO4), and concentrate. Chromatography on silica gel (0–20% ethyl acetate in hexane) to give the title product.
