Reaction Steps

A tube was charged with mixture of 84 (200 mg, 0.77 mmol), 53 (181 mg, 0.77 mmol) and DIPEA (200 mg, 1.5 mmol) in IPA (5 mL), sealed and stirred at 120° C. overnight. The reaction mixture was cooled to RT and concentrated under reduced pressure. The crude residue was purified by SiO2 chromatography eluting with a MeOH/DCM gradient (5% to 15% MeOH) to afford 68 mg (19%) of (±)-N4-(5-cyclopropyl-1H-pyrazol-3-yl)-N2-methyl-N2-(1-(1-(tetrahydro-2H-pyran-2-yl)-1H-benzo[d]imidazol-5-yl)ethyl)pyrimidine-2,4-diamine (86) as white solid: MS (ESI) m/z=459.2 (M+1).
