Designing a Synthesis

Organic synthesis is a branch of chemical synthesis that involves the planned construction of organic compounds/molecules from smaller units that possess functional groups. Friedrich Wöhler was the first scientist who designed the synthesis of an organic compound, urea from inorganic starting materials silver cyanate with ammonium chloride via a simple, one-step synthesis.

Question

How would you prepare the product from the given starting material? Show the retrosynthetic analysis. Show all reaction steps and give reagents. You do not need to show intermediates or mechanisms. The number of arrows does not indicate the number of steps, but just indicate that there are multiple steps.

Make sure to show the retrosynthetic analysis and the reaction steps (label which is the analysis and which are the steps.
