Participants

Reaction Steps

(1S,2R,3S,5R)-3-Amino-5-(6-amino-2-chloro-purin-9-yl)-cyclopentane-1,2-diol trifluoroacetate (20 mg, 39 μmol) and diisopropylethylamine (25 mg, 190 μmol) are placed in a flask with dry THF (1 ml). Mesyl chloride (4.5 mg, 39 μmol) is added and the reaction mixture is stirred at room temperature. The reaction is shown to be complete by LCMS after 3 hours. The solvent is removed in vacuo and the title compound is obtained after purification by reverse phase column chromatography (Isolute™ C18, 0-100% acetonitrile in water—0.1% TFA). MS (ES+) m/e 363 (MH+).
