Reaction Steps

To a flask charged with 2-(3-bromo-2-hydroxymethyl-phenyl)-6-cyclopropyl-3,4-dihydro-2H-isoquinolin-1-one (3.70 g, 9.9 mmol), 1-Methyl-6-[4-(morpholine-4-carbonyl)-phenylamino]-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyridin-2-one (4.38 g, 9.9 mmol), Pd2 (dba)3.CHCl3 (229 mg, 0.25 mmol), 2-Dicyclohexylphosphino-2′,4′,6′-Tri-i-Propyl-1,1′-Biphenyl (238 mg, 0.50 mmol), and K3PO4 hexahydrate (7.5 g, 20 mmol) was added 40 mL of 4:1 dioxane:water and the mixture heated to reflux for 4 h, cooled and filtered over Solka-Floc®, rinsing with ethyl acetate. Partitioned and washed the organic phase with water and brine. Dried over sodium sulfate, filtered and concentrated to afford a dark oil. Purification by silica gel chromatography (methylene chloride/methanol) afforded 3.2 g of 6-Cyclopropyl-2-(2-hydroxymethyl-3-{1-methyl-6-[4-(morpholine-4-carbonyl)-phenylamino]-2-oxo-1,2-dihydro-pyridin-4-yl}-phenyl)-3,4-dihydro-2H-isoquinolin-1-one as a colorless solid. MS (ESI) 606.1 (M+H)+.
