Patent ID: 7507818

Claim:
A process for preparing an alkoxycarbonylaminotriazine of the formula I: wherein Y 1 is hydrogen, C 1 -C 4 -alkyl, phenyl optionally substituted by C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy or halogen, or a radical of the formula NR 5 R 6 and R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are each independently hydrogen or a radical of the formula COOX or X where X is C 1 -C 13 -alkyl whose carbon framework may be interrupted by 1 or 2 oxygen atoms in an ether function and/or be substituted by hydroxyl, or C 3 -C 6 -alkenyl, with the proviso that at least one of the radicals R 1 to R 4 in formula I or, when 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 the formula II: wherein Y 2 is hydrogen, C 1 -C 4 -alkyl, amino or phenyl optionally substituted by C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy or halogen, and R 1 to R 4 are each as defined above, with the proviso that, in formula II, when Y 2 is not amino, at least one of the radicals R 1 R 4 is hydrogen, with a cyclic carbonic ester-of the formula III in the presence of an alcohol and of a base, wherein L is ethylene, 1,2- or 1,3-propylene, or 1,2-, 1,4-, 2,3-, or 1,3-butylene, and also optionally with a minor amount of an acyclic carbonic ester of the formula IV Z 1 O—CO—OZ 2 (IV) wherein Z 1 and Z 2 are each independently C 1 -C 8 -alkyl, and and a C 1 -C 13 -alkanol whose carbon framework may be interrupted by 1 or 2 oxygen atoms in an ether function and/or be substituted by hydroxyl, or a C 3 -C 6 -alkenol, in the presence of an alkali metal alkoxide or alkaline earth metal alkoxide as a base.
