HETEROCYCLIC DERIVATIVES OF PURINES. 5. NUCLEOPHILIC SUBSTITUTION IN SERIES OF IMIDAZOPURINE DERIVATIVES

The chlorination of 1,8-dimethyl-7-phenylimidazoxanthine with an equimolar amount of PCl5 in POCl3 leads to 2,4-dichloro-8-methyl-7-phenylimidazopurine.The possibility of substitution of the halogen atoms in reactions with nucleophilic reage
