A practical three-step synthetic approach to gimeracil in a 68% overall yield is described, using 2,4-dimethoxypyridine as the starting material with 3,5-dichloro-2,4-dimethoxypyridine and 3,5-dichloro-2,4-dihydroxypyridine as intermediates. The advantages of this procedure include short reaction steps, simple operation and good yield.
