Using prostaglandin, the glaucoma drug bimatoprost is synthesized in two steps. A method for this conversion is to be suggested. Concept introduction: The amide can be prepared by the nucleophilic substitution of acyl chloride by the amine. Two moles amines used with one mole of acyl chloride, because one amine molecule acts as a nucleophile and the second acts as a Brønsted base. The carboxylic acids on reaction with thionyl chloride forms acyl chloride by replacing the hydroxyl group of the carboxylic acid with chlorine atom.

Hi!! Please provide a solution that is handwritten. Ensure all figures, reaction mechanisms (with arrows and lone pairs please!!), and structures are clearly drawn to illustrate the synthesis of the product as per the standards of a third year organic chemistry course. ****the solution must include all steps, mechanisms, and intermediate structures as required. Please hand-draw the mechanisms and structures to support your explanation. Don’t give me AI-generated diagrams or text-based explanations, no wordy explanations on how to draw the structures I need help with the exact mechanism hand drawn by you!!! I am reposting this—ensure all parts of the question are straightforward and clear or please let another expert handle it thanks!!
