Procedure

To a solution of tert-butyl 2,4-dichloro-5H-pyrrolo[3,4-d]pyrimidine-6(7H)-carboxylate (1.00 g, 3.44 mmol) and DIPEA (0.672 mL, 3.86 mmol) at room temperature (20° C.) in DCM (7 mL) was added morpholine (0.33 mL, 3.86 mmol). After 2 h the reaction was diluted with DCM and Sat. NaHCO3. The organic layer was rinsed (brine), dried (anhydrous Na2SO4) and concentrated in vacuo. The desired product was isolated by flash chromatography (silica, 50 g, 0-50% EtOAc in petroleum ether (40-60) over 25 min) as a white solid (0.63 g, 1.85 mmol, 54% yield).
