Reaktionsschritte

While J. Org. Chem., 30, 2398 (1965) describes that methylpyrimidine-4-carboxylate can be synthesized by treating 5-bromo-2-methylthiopyrimidine-4-carboxylic acid with Raney-nickel, as described in J. Chem. Soc., 1953, 3129, to give pyrimidine-4-carboxylic acid, and heating the obtained compound in methanol in the presence of concentrated hydrochloric acid. This method is problematic in the availability of the starting materials.
