3-d]pyrimidine derivatives 15. The mechanism of formation of these products must involve reaction of the carbodiimide intermediate with the amidine precursor and cyclisation of the resulting guanidine derivatives 19. The corresponding tetraphenylguanidine 21 was prepared and underwent thermalcyclisation but the quinazoline derivative formed 23 was shown to occur via an alternative cyclisationmechanism. The
