Finally, as a consequence of the solid-liquid phase transfer catalysis method, these intermediates reacted with 2- chloroethyl alcohol to prepare the final new products 1-hydroxyethyl-2-substituted phenoxymethyl benzimidazoles (c1-c5) in high yield.
Following an introduction to the topic of process development, chapter topics include chiral technology, strategies to simplify organic reactions and processes, choosing a reagent, phase transfer catalysis, purity and purification, and safety assessment.
