Extracurricular laboratory: Synthetic route of 2-Chloro-5-ethylpyrimidine

The synthetic route of 111196-81-7 has been constantly updated, and we look forward to future research findings.

Synthetic Route of 111196-81-7 , The common heterocyclic compound, 111196-81-7, name is 2-Chloro-5-ethylpyrimidine, molecular formula is C6H7ClN2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

General procedure: In a reaction vial designed for microwave heating, the considered alkoxypyrazole (2 mmol), the considered halogenated heteroaryl (2.2 mmol) and cesium carbonate (2.8 mmol) were stirred in dimethylformamide or acetonitrile (3 mL) as specified in the examples. This was heated using a microwave at a temperature between 120 C and 180 C for the individually specified duration. The resulting suspension was diluted in water, extracted with ethyl acetate and the organic layer was washed with brine, dried over magnesium sulfate and concentrated to dryness. The residue was further purified as described below.

The synthetic route of 111196-81-7 has been constantly updated, and we look forward to future research findings.
