0.068 g	With tris-(dibenzylideneacetone)dipalladium(0); caesium carbonate; johnphos; In 1,4-dioxane; at 100℃; for 16h;Inert atmosphere;	A solution of 9-(2-benzyl-6-chloro-3-oxo-2,3-dihydropyridazin-4-yl)-1-(3,4- difluorophenyl)-1,9-diazaspiro[5.5]undecane-2-one (0.100 g, 0.200 mmol) and 2- azaspiro[3.3]heptane hydrochloride (0.053 g, 0.40 mmol) in dioxane (6 mL) was stirred with argon purging for ten minutes. Cs2CO3 (0.195 g, 0.600 mmol) was added to the reaction mixture under argon purging followed by the addition of Pd2(dba)3 (30 mg, 0.040 mmol) and JohnPhos (10 mg, 0.040 mmol). The mixture was heated at 100C for 16 h. After cooling to RT, water was added to the reaction mixture and it was extracted with EtOAc, washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. Purification by silica gel chromatography (60-70% EtOAc:hexane) provided the title compound as a white solid (0.068 g, 0.12 mmol).1H NMR (400 MHz, chloroform-d) δ 7.46 - 7.34 (m, 2H), 7.24 - 7.09 (m, 2H), 6.95 - 6.82 (m, 1H), 6.82 - 6.69 (m, 1H), 5.64 (s, 1H), 5.09 (s, 2H), 3.9 - 4.05 (m, 3H), 3.8 (s, 3H), 2.65 - 2.75 (m, 2H), 2.58 - 2.61 (m, 2H), 2.14 (t, 3H), 1.98 - 2.12 (m, 4H), 1.8 - 1.92 (m, 4H), 1.7 - 1.78 (m, 3H); m/z = 560.3 [M+H]+; tR = 1.64 min (LCMS method j)
