Hydrochloric Acid → 2-Hydroxypyrimidine-4,6-dicarboxylic acid

Participants

Reaction Steps

Next, to a stirred solution of 2-chloro-pyrimidine-4,6-dicarboxylic acid monomethyl ester (120 mg, 0.55 mmol) in THF (3 mL) is added 1N NaOH (1.10 mL) and the mixture is stirred at room temperature for 18 hours. The solution is carefully acidified with 1N HCl and the solvent is removed under reduced pressure to give 2-hydroxypyrimidine-4,6-dicarboxylic acid. This is used as is in subsequent reactions.
