All these advantages have been recognized by the industry and pharma processes are currently converting from batch to flow in a high rate. The US FDA (Federal Drug Administration) has recognized the strong impact of continuous manufacturing on product quality and therefore supports the conversion from batch to flow. Novartis expects that continuous manufacturing in the pharmaceutical industry has the potential to cut drug manufacturing time by 90% and drug manufacturing costs by 30-50%. ( new-drug-manufacturing-tools-change-pharma-chemistry). As an example, we have found that butyllithium processes (bromo/lithium exchange and deprotonations) are significantly improved by simply using butyllithium in higher concentration (> 2.5 mol/L). Why change from batch to flow? Flow chemistry serves to achieve process intensification and it is an efficient tool to implement green chemistry principles. Frequently, the reaction concentration can be increased and higher room/time yield be achieved hence. Besides process intensification, there are safety advantages for the case of toxic or thermally labile materials involved and/or high exothermicity of the reaction. Energy savings are realized due to less specific cooling needs. Panel Discussion on FLOW CHEMISTRY In this issue, we present a Panel Discussion on manufacturing using flow chemistry . This topic is of particular interest as the importance of micro reactor technology and flow chemistry in industrial manufacturing is rapidly rising; we have testimony of this because of the high number of companies that showed willingness to participate in this discussion around a virtual table.
