Example 4.128- [ [2- [(1 ,3-Dimethylpyrazol-4-yl)aminol -5-fluor o-4-pyridyll aminol -2-methyl-3,4- dihydroisog uinolin- 1-one A mixture of 8-[(2-chloro-5-fluoropyridin-4-yl)amino]-2-methyl-3,4- dihydroisoquinolin- 1-one (100 mg, 0.33 mmol), l,3-dimethylpyrazol-4-amine (48 mg, 0.43 mmol), sodium tert-butoxide (51.5 mg, 0.54 mmol) and 9,9-dimethyl-4,5- bis(diphenylphosphino)xanthene (41.4 mg, 0.07 mmol) in anhydrous dioxane (3 mL) was degassed with nitrogen and then bis(dibenzylideneacetone)palladium (32.7 mg, 0.057 mmol) was added. The mixture was heated at 15O0C for 30 minutes in a microwave reactor. MeOH was added and the mixture loaded onto an SCX column. The product was eluted first with MeOH and then with a 7M solution of NH3 in MeOH. Fractions containing product were combined and evaporated. The residue was purified by preparative HPLC and fractions containing product were combined and evaporated to afford example 4.12 (50.1 mg, 40% yield); 1H NMR spectrum (300 MHz, DMSO): delta 2.09 (3H, s), 2.95 (2H, t), 3.05 (3H, s), 3.55 (2H, t), 3.70 (3H, s), 6.83 – 6.85 (2H, m), 7.38 – 7.43 (2H, m), 7.85 (IH, s), 7.89 (2H, t), 11.24 (IH, s); Mass spectrum: m/z (ESI+) (M+H)+ = 381.56.
