실험 절차

To an ice cooled stirring solution of 2-[(2-cyclopropylethyl)oxy]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (6.53 g) in chloroform (75 ml), was added N-bromosuccinimide (4.02 g). The reaction mixture was allowed to warm to room temperature and after 16 h treated with water and extracted twice with DCM. The combined extracts were washed with dilute sodium metabisulphite then dilute brine, dried by passing through a hydrophobic frit and evaporated to give the title compound as an orange foam, yield 7.96 gm.
