실험 절차

N-Bromosuccinimide (12.16 g, 68.3 mmol) was added portionwise over 5 mins. to a stirred solution of 2-{[(1S)-1-methylbutyl]oxy}-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (14.9 g, 48.8 mmol) in chloroform (80 ml) at <5° C. under an atmosphere of nitrogen. The reaction mixture was stirred at <5° C. for 5 hours then washed with saturated sodium hydrogen carbonate solution (80 ml) then water (80 ml). The foam was dissolved in DCM (50 ml) and washed with water (50 ml) then brine (50 ml). The combined aqueous phases were washed with DCM (50 ml). The combined organic layers were dried through a hydrophobic frit, and the solvent removed in vacuo to yield the title compound as an orange foam (18.5 g).
