実験手順

To a mixture of 4-(2-chloro-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)morpholine (5 g, 20 mmol) in THF (100 mL) at −78° C. was added tetramethylethylenediamine (3.5 mL, 23 mmol) followed by 2.5 M of n-BuLi (9.3 mL, 23 mmol) dropwise. The reaction was stirred at −78° C. for 1 hour and then N,N-dimethylformamide (2.4 mL, 31 mmol) was added, continue stirred for 1 hours at −78° C. The reaction was quenched with water and extracted with EtOAc. The organic extracts were washed with water, brine, dried over MgSO4 and concentrated. The crude material was triturated with EtOAc to give pure 2-chloro-6-morpholino-9-(tetrahydro-2H-pyran-2-yl)-9H-purine-8-carbaldehyde as a white solid (4.5 g, 80% yield). LC/MS (ESI+): m/z 353 (M+H)
