8-(2,5-dichloropyridin-4-ylamino)-2-methyl-3,4-dihydroisoquinolin-1(2H)-one (100 mg, 0.31 mmol), 1-methyl-1H-pyrazol-5-amine (60.3 mg, 0.62 mmol), sodium 2-methylpropan-2-olate (44.7 mg, 0.47 mmol), 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (38.7 mg, 0.06 mmol) and TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM (28.4 mg, 0.03 mmol) were suspended in dioxane (2 mL) and sealed into a microwave tube. The reaction was degased, purged with nitrogen and heated to 140 °C for 5 minutes in the microwave reactor. Reaction was filtered, washed with CH2Cl2 and concentrated to dryness. The reaction mixture was purified by preparative HPLC using a Waters X-Bridge reverse-phase column (5 microns silica, 30 mm diameter, 150 mm length) and decreasingly polar mixtures of water (containing 0.2% ammonium carbonate) and acetonitrile as eluent. The fractions were evaporated to dryness to afford 8-(5-chloro-2-(1-methyl-1H-pyrazol-5-ylamino)pyridin-4-ylamino)-2-methyl-3,4-dihydroisoquinolin-1(2H)-one (36.0 mg, 30.3 %) as an off-white solid.
