Abstract

The invention comprises compounds of formula <FORM:0837337/IV(c)/1> wherein R is a phosphoric acid radical. They are used in the treatment of leukaemia. They are prepared by coupling a diazobenzene phosphoric acid with 2 : 4 : 6-triaminopyrimidine. In examples m- or p-aminophosphonobenzene is diazotized and coupled with 2 : 4 : 6-triaminopyrimidine to give (21 : 41 : 61-triaminopyrimidinyl - 51 - azo) - benzene - 3 - or - 4 - phosphonic acid as a yellow powder.
