Patent ID: 7371856

Claim:
A process for preparing one or more alkoxycarbonylaminotriazines of formula (I) wherein Y 1 is hydrogen, C 1 -C 4 -alkyl, phenyl unsubstituted or substituted by C 1 -C 4 alkyl, C 1 -C 4 alkoxy or halogen, or is a radical of the formula NR 5 R 6 ; and R 1 , R 2 , R 3 , R 4 , R 5 and R 6 independently of one another are each hydrogen, or a radical of the formula COOX, or X, wherein X is C 1 -C 13 alkyl, whose carbon skeleton may be interrupted by 1 or 2 oxygen atoms in ether function, with the proviso that at least one of the radicals R 1 to R 4 or, if Y 1 is NR 5 R 6 , at least one of the radicals R 1 to R 6 , is COOX, comprising reacting a triazine of formula II wherein Y 2 is hydrogen, C 1 -C 4 alkyl, amino or phenyl unsubstituted or substituted by C 1 -C 4 alkyl, C 1 -C 4 -alkoxy or halogen, with the proviso that in formula (II), if Y 2 is not amino, at least one of the radials R 1 to R 4 is hydrogen, and R 1 to R 4 are each defined as above, with a carbonic ester in the presence of an alcohol and a base, which comprises reacting the triazine of formula (II) with dimethyl carbonate and a C 2 -C 13 alkanol whose carbons skeleton may be intermpted by 1 or 2 oxygen atoms in ether function, in the presence of an alkali metal methoxide or alkaline earth metal methoxide as the base, to form the one or more alkoxycarbonyltriazines of formula (I), in the form of a reaction mixture, wherein the resultant reaction mixture is worked up, wherein the work up is conducted in the absence of any additional solvents, and wherein the work up is conducted by extraction, washing, or extraction and washing.
