| titleOfInvention | Preparation of 4-methylpyrimidines |
| abstract | A process for the preparation of a 4-methylpyrimidine of the general formula I ##STR1## in which R 1 denotes C 1 -C 20 alkyl, C 3 -C 8 cycloalkyl, aryl, C 7 -C 12 phenalkyl, C 7 -C 12 alkylphenyl, NH 2 , NHCN, OH, and SH, n in which a 1-aminovinyl methyl ketone of the general formula II ##STR2## in which R 2 and R 3 denote C 1 -C 20 alkyl, C 3 -C 8 cycloalkyl, aryl, C 7 -C 12 phenylalkyl, C 7 -C 12 alkylphenyl, C 1 -C 20 hydroxyalkyl or together denote a C 2 -C 7 alkylene chain optionally mono- to tetra-substituted by C 1 -C 4 alkyl and optionally interrupted by oxygen, nitrogen, or sulfur, is caused to react with a carboxamide or amidine or a salt thereof of the general formula III ##STR3## in which R 1 has the aforementioned meanings and x stands for oxygen or NH, at temperatures ranging from 20° to 200° C. and pressures ranging from 0.01 to 50 bar. |
