Procedure

The title compound of Example 119, step 2 (40 mg, 0.16 mmol), 1-(2-bromo-4-ethylsulfonylphenoxy)-2,4-difluorobenzene (60 mg, 0.16 mmol), and Pd(dppf)Cl2 (12 mg, 10%) in 1,4-dioxane (880 μL) and saturated bicarbonate solution (aq) (220 μL) were reacted, worked up and purified in a manner similar to Example 117. The title compound (18 mg, 27%) was obtained as a tan solid. 1H NMR (400 MHz, DMSO-d6) δ 1.13 (t, J=7.33 Hz, 3H) 3.34 (q, J=7.33 Hz, 2H) 3.59 (s, 3H) 6.92-6.98 (m, 1H) 7.19-7.27 (m, 1H) 7.50-7.61 (m, 2H) 7.76-7.84 (m, 2H) 7.92-7.96 (m, 1H) 7.97-8.01 (m, 1H) LCMS (M+H)+=424.
