Abstract: The present invention relates to a method for preparing tris-substituted alkoxycarbonylamino-1,3,5-triazine compounds, which involves reacting an amino-1,3,5-triazine compound such as melamine, for example, in the presence of excess amounts of carbon monoxide and an alcohol, a sub-stoichoimetric amount of a base, a catalyst system that includes a catalytic amount of a primary catalyst of a group VIII metal or metal salt, and a sub-stoichiometric amount of a co-catalyst of a group I-B or lanthanide series metal or metal salt. The reaction is conducted at a temperature, pressure and length of time sufficient to form a tris-substituted alkoxycarbonylamino-1,3,5-triazine compound in a yield of at least about 5 percent, with improved yields of more than 40 percent being conveniently obtained.
