This is a multistep synthesis. Great care must be used throughout to ensure obtaining a sufficient quantity of material to proceed to subsequent steps. A four step reaction wherein each step gives a 70% yield will result in a 24% overall yield (.7 x .7 x .7 x .7). Imagine a 15 step synthesis, which is common in many syntheses of complex products.

Multistep Synthesis When synthesizing complex organic molecules, it is common to have at least a dozen individual transformations whereby the product of one reaction is then used as the starting material for the next reaction. You will have an opportunity to do a multistep synthesis starting with inexpensive, readily available benzaldehyde.
