N-bromobutanimide → 8-Bromo-2-[(1-methylbutyl)oxy]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine

Participants

Reaction Steps

To a solution of 2-[(1-methylbutyl)oxy]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (382 mg) in dry chloroform (4.52 mL) at 0° C. was added NBS (234 mg) in a single portion. The reaction was warmed to room temperature and stirred for 5 h. The reaction mixture was taken up in DCM (20 mL) and was washed with water (30 mL). The organics were separated, dried by passing through a hydrophobic frit and concentrated in vacuo to give a green/brown foam (493 mg).
