Reaction Steps

A mixture of N2-(5-Bromo-2-isopropoxy-4-methyl-phenyl)-5-methyl-N4-[2-(propane-2-sulfonyl)-phenyl]-pyrimidine-2,4-diamine from the previous step (53 mg, 0.099 mmol), 4-{2-[4-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrazol-1-yl]-ethyl}-morpholine (Boron Molecular, 61 mg 0.20 mmol), K3PO4 (58 mg), Pd2(dba)3 (10 mg), and tricyclohexylphosphine (8 mg) in 1 mL of 1,4-dioxane/H2O (3/1 v/v) is heated in a sealed tube at 150° C. for 20 min under microwave radiation. The reaction mixture is filtered through a small plug of Celite and concentrated. Final purification using preparative RP LC-MS affords N2-{2-Isopropoxy-4-methyl-5-[1-(2-morpholin-4-yl-ethyl)-1H-pyrazol-4-yl]-phenyl}-5-methyl-N4-[2-(propane-2-sulfonyl)-phenyl]-pyrimidine-2,4-diamine (37). MS (ES+): 634.3 (MH+).
