Reaction Steps

To a solution of (S)-1-cyclopropyl-3-(4-(4-(3-methylmorpholino)-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-2-yl)phenyl)urea (Example 3) (147 mg, 0.37 mmol) and triethyamine (52 μL, 0.37 mmol) in DMF (3 mL, anhydrous) was added tert-butyl 4-(bromomethyl)piperidine-1-carboxylate (103 mg, 0.37 mmol). The reaction mixture was stirred at 75° C. until LCMS indicated reaction was complete. Solvent was then removed in vacuo. Purified by prep. HPLC (high pH) to afford a brown solid (28.9 mg, 0.049 mmol, 13%).
