Synthetic chemistry is a foundational science for the drug discovery process, with efficient tools for conducting this science representing opportunities to accelerate progress of compounds into the clinic and ultimately medicines to patients. However, the scarcity of complex intermediates in pharmaceutical research motivates the pursuit of reaction optimization protocols on submilligram scales. The development of an automated flow-based synthesis platform, designed from commercially available components, that integrates both rapid nanomole-scale reaction screening and micromole-scale synthesis into a single modular unit will be described. This system was validated by exploring a diverse range of reaction variables in a Suzuki-Miyaura coupling on nanomole scale at elevated temperatures, generating liquid chromatography–mass spectrometry data points for 5760 reactions at a rate of &gt;1500 reactions per 24 hours. The efficiency of this process allows for the rapid exploration of multidimensional chemical space, with applications both in early-stage drug discovery as well as route optimization for large scale compound synthesis.
