I have in this reaction "The synthesis of Indigo" by Baeyer. I am
trying to understand this reaction by seeing the mechanism with
arrows, but I am struggling. I need help with the mechanism (arrow
electron pushing) of this reaction. Thanks.

The acetoacetic ester synthesis is a carbonyl alkylation reaction. It is used to prepare methyl ketones from primary alkyl halides, lengthening the carbon chain by three atoms. Thus, the product can be visualized as being a "substituted acetone." The reaction consists of three steps: generation of the enolate anion followed by S2 reaction with a primary alkyl halide, ester hydrolysis under acid conditions, and decarboxylation. 1. NaOEt 2. H2O* 3. heat Br + - H₃C + CO2 + ETOH Hc...
