Abstract
The ketone intermediate LSN647712 is a key synthetic intermediate for the drug substance lasmiditan manufacturing process. A three-step connected continuous flow process utilizing a Turbo Grignard reagent, N-methylpiperidin-4-ylmagnesium chloride, and lithiated 2,6-dibromopyridine sequentially added to double electrophile (O═C(++) synthon dimethylcarbamyl chloride (DMCC) was developed to deliver the ketone intermediate in a high chemical yield (>85%). This highly productive (>100 g/h lab system) and intensified process (τ ∼ 3 min) yields the product in high purity upon batch reactive crystallization to form a corresponding hydrobromide salt. In addition to the connected plug flow reactor system, the Grignard reagent, N-methylpiperidin-4-ylmagnesium chloride, was also prepared continuously in CSTR as a more soluble LiCl adduct in THF (Turbo Grignard).

Abstract
Pyridyllithiums are ubiquitous intermediates used for the electrophilic functionalization of pyridines. In this work, the isolation of a pyridyllithium is reported. Single crystal XRD revealed a dimer in the solid state. In THF solution it was identified as a monomer using DOSY NMR spectroscopy. Calculations showed that the pyridyllithium is a very electron rich pyridine superbase, which may account for its high reactivity.

Abstract
Flow chemistry involves the use of channels or tubing to conduct a reaction in a continuous stream rather than in a flask. Flow equipment provides chemists with unique control over reaction parameters enhancing reactivity or in some cases enabling new reactions. This relatively young technology has received a remarkable amount of attention in the past decade with many reports on what can be done in flow. Until recently, however, the question, "Should we do this in flow?" has merely been an afterthought. This review introduces readers to the basic principles and fundamentals of flow chemistry and critically discusses recent flow chemistry accounts.

Abstract
A flow procedure for the metalation of functionalized heterocycles (pyridines, pyrimidines, thiophenes, and thiazoles) and various acrylates using the strong, non-nucleophilic base TMPMgCl⋅LiCl is reported. The flow conditions allow the magnesiations to be performed under more convenient conditions than the comparable batch reactions, which often require cryogenic temperatures and long reaction times. Moreover, the flow reactions are directly scalable without further optimization. Metalation under flow conditions also allows magnesiations that did not produce the desired products under batch conditions, such as the magnesiation of sensitive acrylic derivatives. The magnesiated species are subsequently quenched with various electrophiles, thereby introducing a broad range of functionalities.
