Reaction Steps

A solution of 2-(2-morpholinyl)-4,5,6,7-tetrahydro-1H-benzimidazole (0.8 g, 3.86 mmol), 4,6-dichloro-2-pyrimidinamine (0.633 g, 3.86 mmol) and Hunig's base (1.681 mL, 9.65 mmol) in ethanol (19.3 mL) was heated at 85° C. overnight. The mixture was concentrated and chromatographed (eluent EtOAc+NH4OH) to afford the title compound (200 mg). LC-MS (ES) m/z=335 [M+H]+.
