A mixture of (R)-3-[6-(2-cyclopropyl-methoxy)-pyridin-3-yloxy]-pyrrolidin-2-one (100 mg), 6-bromo-4-fluoro-2,3-dihydro-1H-inden-1-one (92 mg) and 1,4-dioxane (2 mL) was purged with argon. N,N′-Dimethyl-ethylene-diamine (355 mg), cesium carbonate (263 mg) and copper(I) iodide (8 mg) were added. The mixture was heated to 80° C. for 4 hours. After cooling to r.t. the mixture was filtered and the filtrate purified by preparative HPLC to provide Example 1-11. 1H-NMR (400 MHz, DMSO) δ 7.99 (1H, dd, J=11.2, 1.8 Hz), 7.95 (1H, d, J=3.1 Hz), 7.77 (1H, d, J=1.8 Hz), 7.53 (1H, dd, J=9.0, 3.1 Hz), 6.79 (1H, d, J=9.0 Hz), 5.22 (1H, dd, J=8.3, 8.3 Hz), 4.03 (2H, d, J=7.1 Hz), 3.96 (1H, m), 3.86 (1H, m), 3.10 (2H, m), 2.72 (2H, m), 2.68 (1H, m), 2.13 (1H, m), 1.22 (1H, m), 0.54 (2H, m), 0.30 (2H, m).
