Abstract
Condensation of N-(4-hydroxy-3,5-di-tert-butylphenyl)biguanide with esters in the presence of catalytic amounts of sodium ethylate gives 2-amino-4-(4-hydroxy-3,5-di-tert-butylanilino)-6-substituted sym-triazines. When the trichloroacetate ester is used the main product is 2-amino-4-(4-hydroxy-3,5-di-tert-butylanilino)-6-oxo-1(5)H-sym-triazine.
