Carbon Dioxide → 5-Chloro-2-methanesulfonylpyrimidine

Participants

Reaction Steps

5-Chloro-2-(methylsulfonyl)pyrimidine-4-carboxylic acid (5.7 g, 24 mmol) was refluxed in anisole (8 mL) until the evolution of carbon dioxide ceased. The reaction mixture was cooled to room temperature and filtered. The solid was washed with light petroleum ether (1×50 mL) and dried to obtain the title compound (4.10 g, 88% yield) as a light orange solid.
