Reaction Steps

A mixture of 62.5 (0.100 g, 0.48 mmol), 4-(trifluoromethyl)benzeneboronic acid 61.1 (0.183 g, 0.97 mmol), K2CO3 (0.200 g, 1.45 mmol), and Pd(PPh3)4 (0.056 g, 0.05 mmol) in toluene (3.2 mL) was stirred overnight at 100° C. The mixture was cooled to room temperature, filtered through a pad of silica gel (EtOAc), and concentrated. The crude product was chromatographed on silica gel (0-30% EtOAc/hexane) to afford 62.6 (0.063 g, 48%) as an oil. 1H NMR (400 MHz, CDCl3) δ 7.66 (d, 2H), 7.61 (d, 2H), 7.14 (s, 1H), 4.79 (s, 2H), 2.27 (s, 3H).
