PCT No. PCT/JP94/01190 Sec. 371 Date Feb. 5, 1996 Sec. 102(e) Date Feb. 5, 1996 PCT Filed Jul. 20, 1994 PCT Pub. No. WO95/03287 PCT Pub. Date Feb. 2, 1995A method for alkylation of at least one or more amino groups or mono-substituted amino groups, each on a carbon atom of a triazine ring of 1,3,5-triazine derivatives (melamine, melamine derivatives and various kinds of guanamine derivatives and the like), which includes reacting the 1,3,5-triazine derivatives having at least one or more amino groups or mono-substituted amino groups with alcohols in the presence of a catalyst of a metal of group VII and/or group VIII in the periodic table. The object of the invention is to provide a method for alkylation of 1,3,5-triazine derivatives, which includes alkylating amino groups or mono-substituted amino groups in carbon atoms of a 1,3,5-triazine ring, whereby substituted 1,3,5-triazine derivatives which are a group of useful compounds and which are widely used as intermediates of fine chemicals such as agricultural chemicals, medications, dye-stuffs, paints and the like, as resin materials and as flame-retardant materials can be easily produced in high yields.
