Procedure

To tris(dibenzylideneacetone)dipalladium (0) (0.0147 g, 0.0160 mmol), xantphos (0.0186 g, 0.0321 mmol), Cs2CO3 (0.0975 g, 0.299 mmol), 2-(1-(6-chloropyridin-3-yl)piperidin-4-yl)acetonitrile (0.0504 g, 0.214 mmol), and compound 245 (0.0580 g, 0.214 mmol) was added degassed (Ar) dioxane (1.0 mL). The reaction was stirred at 105° C. overnight. After 16 h, the reaction was cooled to room temperature and loaded directly onto silica gel. Crystallization from THF and HCl salt formation provided compound 252 (55 mg). 1H NMR (400 MHz, DMSO-d6) δ 1.43 (d, J=10.56 Hz, 2 H) 1.66-1.81 (m, 2 H) 1.86 (d, J=11.35 Hz, 3 H) 2.05 (d, J=6.26 Hz, 2 H) 2.15 (br. s., 2 H) 2.19-2.31 (m, 2 H) 2.59 (d, J=5.87 Hz, 2 H) 2.85 (t, J=11.74 Hz, 2 H) 3.75 (d, J=12.13 Hz, 2 H) 5.53 (quin, J=9.10 Hz, 1 H) 7.68 (d, J=9.39 Hz, 1 H) 8.00 (br. s., 1 H) 8.15 (d, J=5.09 Hz, 1 H) 8.20 (dd, J=9.39, 2.74 Hz, 1 H) 8.30 (dd, J=4.89, 2.93 Hz, 1 H) 9.55 (s, 1 H) 11.80 (br. s., 1 H) ppm.
