| titleOfInvention | Production of pyrimidine derivative |
| abstract | PURPOSE: To obtain a pyrimidine derivative useful as an intermediate for a herbicide by one process easily, by reacting dimethyl-1,3-propanediimidate with an alkoxycarbonyl isothiocyanate as raw materials. n CONSTITUTION: A free dimethyl-1,3-propanediimidate shown by the formula I is reacted with an alkoxycarbonyl isothiocyanate shown by the formula II (R is alkyl) in an organic solvent such as toluene, etc. at -10°C the reflux temperature of the solvent, and, if necessary, an equivalent amount of aqueous solution of alkali (bi)carbonate to suppress side reactions (yield is improved), to give a 2-alkoxycarbamoyl 4,6-dimethoxypyrimidine derivative shown by the formula III. This compound is recrystallized with hexane, etc., so that it is easily purified. Used as an intermediate for N-4,6- dimethoxypyrimidinesulfonylurea derivative as a herbicide. n COPYRIGHT: (C)1986,JPO&Japio |
