A practical synthesis of 2-[3-(4-fluoro-3-pyridin-3-yl-phenyl)-imidazo[1,2-a]pyrimidin-7-yl]-propan-2-ol (1), an oral GABA(A) alpha(2/3)-selective agonist, is described. The five-step process, which afforded 1 in 40% overall yield, included imidazopyrimidine 2 and pyridine boronic acid 4 as key fragments. The synthesis is highlighted by consecutive

Conducting low-temperature organometallic reactions under continuous flow conditions offers the potential to more accurately control exotherms and thus provide more reproducible and scalable processes. Herein, progress towards this goal with regards to the lithium-halogen exchange/borylation reaction is reported. In addition
