Reaction Steps
To the title compound of Step A (0.12 g, 0.27 mmol), 3-methylphenylboronic acid (0.08 g, 0.60 mmol), K3PO4 (0.128 g, 0.54 mmol), Pd(dppf)Cl2.CH2Cl2 (0.013 g, 0.017 mmol) and dppf (0.006 g, 0.010 mmol) was added dioxane (3 mL). The flask was heated at 100° C. for 18 h, cooled to rt, diluted with EtOAc and filtered through a small silica pad. Silica gel chromatography (10-40% EtOAc in hexanes) gave 0.073 g (72% yield) of the title compound. 1H NMR (CDCl3): 7.31-7.26 (m, 4H), 7.18-7.15 (m, 1H), 7.05 (dd, J=8.2, 2.0 Hz, 1H), 6.57 (d, J=1.9 Hz, 1H), 4.86-4.81 (m, 1H), 4.30-4.26 (m, 2H), 3.96 (dd, J=10.2, 4.2 Hz, 2H), 2.40 (s, 3H), 1.44 (s, 9H).
