More Information
Summary:The invention relates to a range of original xanthine derivatives substituted in 1 -and 7-positions with benzhydryl-4-piperazinyl-1-alkane fragments. A method for obtaining 3-methyl-7-[4-(benzhydryl-4-piperazinyl-1)butyl]xanthine and the salts thereof with organic and inorganic acids by alkylating the 7-potassium salt of 3-methylxanthine by 1,4-dibromobutane, by subsequently interacting the thus formed 7-(4-bromobutyl)-3-methylxanthine with 1-benzhydrylpiperazinyl and by neutralising the thus obtained radical 7-/4-(4-benzhydrylpiperazinyl-1) butyl/-3-methylxanthine by an organic or inorganic acid is also disclosed.
