Step 1: Preparation of the Precursor
The production of Ethyl 4-pyrimidineacetate begins with the preparation of the precursor, which is 2-chloro-4-nitroaniline.
This compound is synthesized by the reaction of aniline with nitric acid and sodium chloride.
The reaction produces 2-chloro-4-nitroaniline, which is then treated with hydrogen chloride to remove the nitro group.

Step 2: Esterification
The next step in the production of Ethyl 4-pyrimidineacetate is the esterification of 2-chloro-4-nitroaniline with ethanol in the presence of a strong acid catalyst such as sulfuric acid.
The reaction produces Ethyl 4-nitrobenzoate, which is then treated with a base such as sodium hydroxide to convert it into Ethyl 4-pyrimidineacetate.

Step 3: Purification
The product obtained from the esterification step is generally impure and contains contaminants such as nitro groups and other organic impurities.
To obtain pure Ethyl 4-pyrimidineacetate, the product is purified by various methods such as crystallization, distillation, and chromatography.
The purification step is crucial as it ensures the final product meets the required purity standards.

Step 4: Characterization
