API SYNTHESIS INTERNATIONAL: MIANSERIN

In a different method reaction of styrene oxide (XV) with methylamine provided amino alcohol (XVI) which was further condensed with ethylene oxide (XVII) to afford amino diol (XVIII) Alternatively diol (XVIII) was prepared by a more direct procedure by condensation of epoxide (XV) with 2-(methylamino)ethanol (XIX) Chlorination of (XVIII) employing SOCl2 yielded the dichloro derivative

Slow anion and conformational exchange on the 1H NMR time scale at low temperature coupled with NMR titration results in a high level of understanding of the anion-binding properties of the compounds particularly with respect to significant conformational change resulting from induced fit complexation Peak selectivity for halides particularly Cl- is observed The approach has been

According to energy dispersion spectroscopy (EDS) analysis and X-ray diffraction (XRD) patterns PbClF particles were left as residues on the substrate after etching using 1BHF:2HCl:4NH 4 Cl:4H 2 O solution Therefore an additional 2HNO 3:1H 2 O etching process was applied to convert PbClF to PbCl 2 which can be dissolved completely in

styrene copolymerization reaction

When traces of the CO/styrene polyketones are also formed their 13C-NMR characterization shows that they are stereochemically homogeneous with a unique syndiotacticity This result implies that Pd-complexes able to induce a complete enantioface discrimination in the insertion step of the alkene during the catalytic cycle of the styrene alternate carbonylation have been produced for the first

Computer program for reducing mass spectral data from

MASS MAX ANALYSIS A second and more sophisticated approach to mass spectral deconvolution 3 has been taken by Biemann and co-workers This approach makes use of the principle that when a compound elutes from a GC column and is analyzed by continuous scan MS the ions of each component show maximum intensity at some mean elution time The algorithm chosen then searches through
