실험 절차

The mixture of 4-chloro-3-(trifluoromethyl)phenol (3.2 g, 16.28 mmol), 4-fluorobenz aldehyde (2.425 g, 19.54 mmol) and K2CO3 (3.38 g, 24.42 mmol) in DMF (25 mL) was heated with a microwave reactor at 120° C. for 20 min. Purification via an ISCO system then afforded the title compound as a yellow solid (4.9 g, 100% yield). LCMS: rt=3.78 min, [M+H+]=300.9
