Procedure

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) (50 mg 0.13 mmol) in dioxane (3 mL) at room temperature (20° C.) was added sodium hydrogencarbonate (22 mg 0.26 mmol) followed by ethyl chloroformate (14 uL 0.15 mmol). The reaction mixture was stirred for 16 h. The solvent was removed in vacuo and the residue partitioned between DCM and water. The organic phase was passed through a 1 micron PTFE filter to dry and then evaporated in vacuo to afford (38 mg 64%).
