Arylamidines 2 react with 5-methoxymethylen-2,2-dimethyl-1,3-dioxan-4,6-dione 5 to give 2,4-diaryl-1,3,5-triazines in moderate to good yields. 5 can be comprehended as a formic acid derivative which transfers a C-1-building block. Other formic acid derivatives give only poor to moderate yields of triazines by treatment with amidines. The synthetic method is applicable to aromatic amidines.
