Procedure

A process for making 1,3-dicyclopropylmethyl-8-amino xanthine which process comprises reacting 1,3-dicyclopropylmethyl xanthine with nitric acid to yield 1,3-dicyclopropylmethyl-8-nitro xanthine and thereafter reducing the nitro group to an amino group to yield 1,3-dicyclopropylmethyl-8-amino xanthine.
