Reaction Steps

To a stirring solution of (R)-1-cyclopropyl-3-(3-fluoro-4-(4-(3-methylmorpholino)-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-2-yl)phenyl)urea hydrochloride (intermediate 33) (112 mg, 0.25 mmol) in DMF (2 mL) was added NEt3 (70 μl, 0.5 mmol), and methanesulfonyl chloride (21 μL, 0.275 mmol). Reaction was stirred at room temp overnight. The reaction mixture was concentrated in vacuo before partitioning between DCM (10 ml) and water (10 ml). The organic layer was recovered, passed through a hydrophobic frit and the solvent removed in vacuo. Residue was then purified by prep. HPLC at high pH to afford the compound title compound as a light brown solid (30 mg, 0.06 mmol, 24%).
