Reaction Steps

To a flask was added 1-bromomethyl-2,4-bis-trifluoromethyl-benzene (2.27 g, 7.39 mmol), vanillin (1.12 g, 1 equiv), DMF (23 mL) and fine mesh K2CO3 (5.11 g, 37 mmol). The reaction slurry was stirred at 70° C. for 15 h. The reaction solution was diluted with EtOAc (120 mL), filtered through a Buchner funnel, washed with sat NH4Cl (50 mL×2), dried over Na2SO4, filtered, and concentrated. The crude material was chromatographed (SiO2, Hex/EtOAc: 100:0 to 70:30) to yield intermediate product (2.79 g, 86%). 1H NMR (400 MHz, CDCl3) δ 9.88 (s, 1H), 7.97 (d, J=8 Hz, 1H), 7.96 (s, 1H), 7.85 (d, J=8 Hz, 1H), 7.48 (s, 1H), 7.42 (d, J=8 Hz, 1H), 6.93 (d, J=8 Hz, 1H), 5.48 (s, 2H), 3.99 (s, 3H); MS (ESI) 379 (MH+).
