ABSTRACT:
Purine derivatives of formula I, substituted at the 9-position, are prepared from a chloro substituted purine starting material, first making an alkyl substitution at the 9-position, then forming the desired esterified side chain, reducing this and hydrogenating the resultant diol prior to addition of alkyl carbonyl groups.
