Reaction Steps

60 Parts (1.0 mole) of urea, 30 parts (1.0 mole) of paraformaldehyde, 72 parts (1.0 mole) of isobutyraldehyde, 92 parts (1.5 moles) of ethylene glycol, 46 parts (2.6 moles) of water, and 10 parts of 40% sulfuric acid were stirred together and heated at 70° C. until a clear solution of an equilibrium mixture of 5,5-dimethylpyrimid-3-en-2-one and 5,5,-dimethyl-4-hydroxyethoxypyrimid-2-one was formed, confirmed by IR spectra.
