Procedure

Diketene is converted at a temperature of +30° to -40° C. with HCl into the acetoacetic acid chloride. 2-Chloroacetoacetic acid chloride is then formed by introduction of chlorine at a temperature of +30° to -40° C. The chloride is converted by the addition of 1 mole of the corresponding amine and 1 mole of tertiary base, such as triethylamine, or 2 moles of the corresponding amine into the corresponding 2-chloroacetoacetic acid amine.
