Hexane → HCID 54112621, compound

Participants

Reaction Steps

0.065 mL of a 1 mol/L boron tribromide-dichloromethane solution was added to a solution of 9.6 mg of 1-(3,5-bis-O-benzyl-2-deoxy-2-fluoro-4-thio-D-arabinofuranosyl)cytosine in 1 mL of dichloromethane under cooling on ice. While the temperature was gradually increased to room temperature, the obtained mixture was stirred for 2 hours. Thereafter, hexane was added to the reaction mixture, and a solid was then collected by filtration. The obtained solid was washed with toluene and ethyl acetate, so as to obtain 5.3 mg of 1-(2-deoxy-2-fluoro-4-thio-D-arabinofuranosyl)cytosine in the form of a white solid.
