Versuchsvorschrift

German OS No. 2,025,247 teaches that orotic acid can be prepared by converting, in a first stage, diketene and chlorine to γ-chloroacetoacetic acid chloride, in a second stage, reacting the γ-chloroacetoacetic acid chloride with urea to form 6-chloromethyluracil, separating the 6-chloromethyluracil and oxidizing the 6-chloromethyluracil with hydrogen peroxide to orotic acid.
