The product from Example 185A (0.1 g, 0.171 mmol), 4-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl)morpholine (0.050 g, 0.171 mmol), potassium phosphate (0.028 mL, 0.343 mmol), tris(dibenzylideneacetone)dipalladium(0) (1.570 mg, 1.715 μmol) and 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamante (1.504 mg, 5.14 μmol) were combined in THF (1.2 mL)/water (0.4 mL). The mixture was sparged with nitrogen for 15 minutes diluted into EtOAc, washed with 1M sodium bicarbonate, brine, dried (Na2SO4), filtered and concentrated. Purification by flash chromatography on an Isco 12 g silica cartridge eluting with 20-70% EtOAc in hexane gave the title compound as a cream colored powder (91 mg, 86%). %). MS (ESI) m/z 620 (M+H)+.
