Reaction Steps

A mixture of 60.2 (0.300 g, 1.55 mmol), 4-n-butylbenzeneboronic acid 60.3 (0.553 g, 3.11 mmol), K2CO3 (0.644 g, 4.66 mmol), and Pd(PPh3)4 (0.180 g, 0.16 mmol) in toluene (5 mL) was stirred overnight at 95° 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 (0-40% EtOAc/hexane) to afford 60.4 (0.072 g, 19%). 1H NMR (400 MHz, CDCl3) δ 7.49 (d, 2H), 7.18 (d, 2H), 7.13 (d, 1H), 6.97 (d, H), 4.82 (s, 2H), 2.62 (t, 2H), 1.60 (m, 2H), 1.37 (m, 2H),
