Lin, Hongkun published the artcileA Rapid Total Synthesis of Ciprofloxacin Hydrochloride in Continuous Flow, HPLC of Formula: 924-99-2, the publication is Angewandte Chemie, International Edition (2017), 56(30), 8870-8873, database is CAplus and MEDLINE.
Within a total residence time of 9 min, the sodium salt of ciprofloxacin was prepared from simple building blocks via a linear sequence of six chem. reactions in five flow reactors. Sequential offline acidifications and filtrations afforded ciprofloxacin and ciprofloxacin hydrochloride. The overall yield of the eight-step sequence was 60 %. No separation of intermediates was required throughout the synthesis when a single acylation reaction was applied to remove the main byproduct, dimethylamine.
