Reaction Steps

To a stirred solution of (S)-2-fluoro-4-(6-methyl-4-(3-methylmorpholino)-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-2-yl)aniline (intermediate 16) (139 mg, 0.40 mmol) in dry THF, was added ethyl isocyanate (70 μL, 0.89 mmol) dropwise. The reaction mixture was stirred at 40° C. for 48 hours, before removal of the solvent in vacuo. The crude material was then purified prep. HPLC (high pH), affording the title compound as a white solid (23.3 mg, 13.7%).
