Palladium diacetate (65.3 mg, 0.291 mmol), Xantphos (168 mg, 0.291 mmol) and Cs2CO3 (284 mg, 0.873 mmol) were each rapidly added in sequence to a suspension of 7-chloro-5-methyl-2-(2-[1,2,4]triazolo[1,5-a]pyridin-2-yl-ethyl)-3,5-dihydro-2H-pyrrolo[3,4-c]pyridine-1,6-dione (100 mg, 0.291 mmol, see Example c6)) and morpholine (25.3 mg, 0.291 mmol) in dioxane (5 ml). The reaction mixture was heated in a microwave at about 120° C. for about 40 min. The solvent was removed and the resulting mixture was purified by preparative HPLC (system: Waters 2767 PHW003, eluent: MeCN/ammonium acetate buffer (gradient: 7:93 to 30:70 over 15 min), column: Boston Analytics, C-18, 10 μm, 10×250 mm) to afford the title compound (17 mg, 0.043 mmol, 14.82% yield).
