実験手順

To a solution of 2-benzylamino-9-ethyl-9H-purin-6-ylamine (1.0 mmol), a compound of formula (4), in 10 mL of dry DMF was added N-bromosuccinimide (267 mg, 1.5 mmol). The reaction mixture was stirred at room temperature for 1 hour. The solvent was then removed in vacuo and the residue partitioned between water and chloroform. The organic layer was washed with 1N sodium hydroxide, dried (Na2SO4), filtered, and the filtrate concentrated in vacuo. The residue was chromatographed on a silica gel column, eluting with chloroform/methanol; (98/2), to give 2-benzylamino-8-bromo-9-ethyl-9H-purin-6-ylamine as a chromatographically pure solid.
