Abstract
Finding and optimising of synthesis processes for active pharmaceutical ingredients (API) is time consuming. In the finding phase, established methods for synthesis, purification and formulation are used to achieve a high purity API for biological studies. For promising API candidates, this is followed by pre-clinical and clinical studies requiring sufficient quantities of the active component. Ideally, these should be produced with a process representative for a later production process and suitable for scaling to production capacity. This work presents an overview of different approaches for process synthesis based on an existing lab protocol. This is demonstrated for the production of the model drug 4,5,6,7-tetrabromo-2-(1H-imidazol-2-yl) isoindolin-1,3-dione (TBID). Early batch synthesis and purification procedures typically suffer from low and fluctuating yields and purities due to poor process control. In a first step the literature synthesis and purification procedure was modified and optimized using solubility measurements, targeting easier and safer processing for consecutive studies.
