Abstract

Method B.--4 solution of 5 g. of 9-benzyl-6-chloropurine17 in 100 ml. of reagent toluene was refluxed and stirred with 25 g. of silver fluoride (AgF, Harshaw Chemical Company) for 1.5 hr. The silver salts were filtered. Evaporation of the toluene filtrate gave 3.5 g. of solid which was recrystallized from benzene-nheptane to give 3.0 g. of needles, mp 124-126". This product was identical to 9-benzyl-6-fluoropurine prepared by method A. 2-Fluoro-9- ...
