2,4-Dichloro-5-pyrimidinecarboxylic acid Use and Manufacturing

To 10.0 g (64.06 mmol) of uracil-5-carboxylic acid (Aldrich Chemical Company) partially dissolved in 20 mL of DMF are added, under cold conditions, 59.7 mL (0.64 mol) of phosphorus oxychloride and 10.3 mL (64.7 mmol) of N, N-diethylaniline, and the mixture is then heated at 90° C. for 2 hours 40 minutes.To a solution of 9 g (42.8 mmol) of 2, 4-dichloro-5-pyrimidinecarboxylic acid chloride (Manchester Organics Limited) in 60 mL of ether are added 10 mL of water and the reaction mixture is stirred vigorously at 35° C. for 1 hour. After addition of ether and separation of the phases by settling, the organic phase is dried over Na
