Ammonia → 2'-Deoxy-4'-C-ethynyl-2-fluoroadenosine

Participants

Reaction Steps

Compound 3 (200 mg, 0.53 mmol) was dissolved in methanol (7.00 ml), and 28% aqueous ammonia (5.00 ml) was added to the resultant solution, followed by stirring at room temperature for four hours. The resultant reaction mixture was concentrated under reduced pressure, and a mixture of chloroform and methanol (20:1) was added to the resultant residue. The thus-precipitated crystals were filtered, and then the resultant crystals were recrystallized from water, to thereby yield compound 4 (113 mg, 0.39 mmol, 73.6%).
