1. When beginning a reaction, have in hand an assay certain to distinguish starting material and product. 2. After the reaction has been optimized, optimize work-up and isolation. 3. Whenever possible, split experiments, varying processing on each stream, and compare. This is particularly useful for optimizing work-up and crystallization. 4.Minimize duplication, unless that is the goal. 5.Reactions causing by-products with extended processing require more attention to scale up. |
