“…Moreover, after several purification attempts the final products still appeared as intense yellow solids, which is not with agreement with the previous literature reports, which describe it as white solids. A possible explanation of the low performance of PBr 3 in dichloroethane is related with the fact that dichloroethane tend to decompose under a high temperature, forming a mixture of various products [24,25], which further react with the remaining components of the reaction mixture, leaving a high amount of impurities. To circumvent this undesired event, we opted to perform the reaction, replacing dichloroethane with non-halogenated solvents.…”

We developed an efficient microwave-assisted three-step synthesis of zolpidem and its fluorinated analogues 1–3. The procedure relays on the utilization of easily accessible and inexpensive starting materials. Our protocol shows superior performance in terms of yield and purity of products, compared to conventional heating systems. Notably, the total time needed for reaction accomplishment is significantly lower comparing to oil bath heating systems. Finally, we have performed a detailed study on the preparation of zolpidem tartrate salt I, and we assessed its particle-sizes using a polarizing microscope. Our goal was to select the appropriate method that generates the acceptable particle-size, since the solid-size directly influences solubility in biological fluids and further bioavailability. We believe that the disclosed procedure will help to produce a lab-scale quantity of zolpidem and its fluorinated derivatives 1–3, as well as zolpidem tartrate salt I, with suitable fine-particle size for further biological experimentation.

Carbon spheres with hierarchical pore structure were successfully synthesized by using strongly basic anion exchange resins exchanged with silicate, followed by pyrolysis in an inert atmosphere and etching silica. As a result of the quaternary ammonium group in the anion exchange resin structure, these carbon spheres were doped with nitrogen. The performance of these carbon spheres in the catalytic dehydrochlorination of 1,2dichloroethane (EDC) was improved with the increase of calcination temperature, and the carbon sphere 900-900-RC showed the highest conversion rate (96.7%) and a selectivity to vinyl chloride above 99%. The structural and surface properties of N-doped carbon spheres were characterized by scanning electron microscopy, nitrogen sorption, and Raman and X-ray photoelectron spectroscopy. The result of these characterizations further verified that the quaternary nitrogen species are as effective as pyridine nitrogen species in this catalyst.
