Reaction Steps
A mixture of 4-(7-bromo-3-methyl-3,4-dihydroisoquinolin-2(1H)-yl)-6-(4-methylpiperazin-1-yl)pyrimidin-2-amine (0.350 g, 0.839 mmol) (Peak 1, Example 49, Step 7), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,6-dihydropyridine-1(2H)-carboxylate (0.311 g, 1.01 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (1:1) (41.1 mg, 0.0503 mmol), potassium carbonate (0.464 g, 3.35 mmol) in 1,4-dioxane (5.0 mL) and water (2.5 mL) was degassed and recharged with nitrogen three times, and heated at 120° C. for 2 h. The reaction was diluted with ethyl acetate and then washed with water and brine, dried over NaSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column eluted with methanol in DCM (0-10%) to afford the desired product (260 mg, 59.7%). LCMS (M+H)+: m/z=520.4.
