Abstract

Substituted guanidine derivatives of the formula I, ##STR1## are prepared by a) reacting calcium cyanamide with an alcohol of the formula R.sup.10 --OH to give an isourea derivative of the formula II, ##STR2## and b) reacting the substituted isourea with a primary or secondary amine of the formula III, ##STR3## where the substituents R.sup.1 and R.sup.2 and R.sup.10 have the meanings explained in the description.
