Reaction Steps

To a solution of ethyl [(1S-5-(3-{[6-chloro-5-(trifluoromethyl)-2-pyridinyl]amino}propoxy)-2,3-dihydro-1H-inden-1-yl]acetate (Example 303, 0.06 9, 0.14 mmol) in a mixture of toluene (3.75 mL), 1,4-dioxane (0.75 mL), and water (0.88 mL) were added Na2CO3 (0.15 g, 1.38 mmol), 4-methoxyphenyl boronic acid (0.08 g, 0.55 mmol), and PdCl2(dppf)CH2Cl2 (0.02 g, 0.03 mmol). The mixture was heated at 80° C. for 4 h, and then concentrated under reduced pressure. The product (0.11 g, 94%) was purified by silica gel flash chromatography (2:1 hexanes /EtOAc). 1H NMR (400 MHz, DMSO-d6) δ 7.66 (d, 1H), 7.39 (t, 1H), 7.33 (d, 2H), 7.04 (d, 1H), 6.94 (dd, 2H), 6.74 (d, 1H), 6.65 (dd, 1H), 6.50 (d, 1H), 4.08 (q, 2H), 3.97 (t, 2H), 3.79 (s, 3H), 3.45-3.30 (m, 3H), 2.76-2.68 (m, 3H), 2.35 (dd, 1H), 2.30-2.20 (m, 1H), 1.95 (qt, 2H), 1.70-1.58 (m, 1H), 1.19 (t, 3H).
