EP0945446A1 — Cyanoethylmelamine derivatives and process for producing the same

USPTO Abstract

The present invention relates to a cyanoethylmelamine derivatives of the formula I: {wherein 1 to 5 of the substituents X' to X 6 represent a cyanoethyl group and at least one remaining group represents a C 1-20 alkyl group, a C 2-20 alkenyl group (said alkyl or alkenyl group may optionally have an alicyclic group or a phenyl group in its structure), a C 5-6 cycloalkyl group or a phenyl group, or two of the substituent groups bonded to the same nitrogen atom together may form an alkylene chain having 2 to 7 carbon atoms, and the remaining substituent or substituents represents a hydrogen atom}. The production of cyanoethylmelamine derivatives can be obtained at high yield by reacting N-substituted melamine derivatives with acrylonitrile or reacting mono- or di-halogeno-N-substituted triazine derivative with aminopropionitrile. The compounds of the formula (I) are useful compounds as intermediates for fine chemicals such as agricultural chemicals, medicines, dye stuffs, paints, etc. and as crosslinking intermediates for resins.
