[0555] Log P Values:
[0556] Measurement of Log P values was performed according to EEC directive 79/831 Annex V.A8 by HPLC (High Performance Liquid Chromatography) on reversed phase columns with the following methods: [0557] .sup.[a] Log P value is determined by measurement of LC-UV, in an acidic range, with 0.1% formic acid in water and acetonitrile as eluent (linear gradient from 10% acetonitrile to 95% acetonitrile). [0558] .sup.[b] Log P value is determined by measurement of LC-UV, in a neutral range, with 0.001 molar ammonium acetate solution in water and acetonitrile as eluent (linear gradient from 10% acetonitrile to 95% acetonitrile). [0559] .sup.[c] Log P value is determined by measurement of LC-UV, in an acidic range, with 0.1% phosphoric acid and acetonitrile as eluent (linear gradient from 10% acetonitrile to 95% acetonitrile).
[0560] If more than one Log P value is available within the same method, all the values are given and separated by +.
[0561] Calibration was done with straight-chain alkan2-ones (with 3 to 16 carbon atoms) with known Log P values (measurement of Log P values using retention times with linear interpolation between successive alkanones). Lambda-max-values were determined using UV-spectra from 200 nm to 400 nm and the peak values of the chromatographic signals.
[0562] NMR-Peak lists
[0563] 1H-NMR data of selected examples are written below in form of 1H-NMR-peak lists. To each signal peak are listed the -value in ppm and the signal intensity in round brackets. Between the -valuesignal intensity pairs are semicolons as delimiters.
[0564] The peak list of an example has therefore the form:
[0565] .sub.1 (intensity.sub.1); .sub.2 (intensity.sub.2); . . . ; .sub.i (intensity.sub.i); . . . .sub.n (intensity.sub.n)
[0566] Intensity of sharp signals correlates with the height of the signals in a printed example of a NMR spectrum in cm and shows the real relations of signal intensities. From broad signals several peaks or the middle of the signal and their relative intensity in comparison to the most intensive signal in the spectrum can be shown.
[0567] For calibrating chemical shift for 1H spectra, we use tetramethylsilane and/or the chemical shift of the solvent used, especially in the case of spectra measured in DMSO. Therefore in NMR peak lists, tetramethylsilane peak can occur but not necessarily.
[0568] The 1H-NMR peak lists are similar to classical 1H-NMR prints and contains therefore usually all peaks, which are listed at classical NMR-interpretation.
[0569] Additionally they can show like classical 1H-NMR prints signals of solvents, stereoisomers of the target compounds, which are also object of the invention, and/or peaks of impurities.
[0570] To show compound signals in the delta-range of solvents and/or water the usual peaks of solvents, for example peaks of DMSO in DMSO-D.sub.6 and the peak of water are shown in our 1H-NMR peak lists and have usually on average a high intensity.
[0571] The peaks of stereoisomers of the target compounds and/or peaks of impurities have usually on average a lower intensity than the peaks of target compounds (for example with a purity >90%).
[0572] Such stereoisomers and/or impurities can be typical for the specific preparation process. Therefore their peaks can help to recognize the reproduction of our preparation process via side-products-fingerprints.
[0573] An expert, who calculates the peaks of the target compounds with known methods (MestreC, ACD-simulation, but also with empirically evaluated expectation values) can isolate the peaks of the target compounds as needed optionally using additional intensity filters. This isolation would be similar to relevant peak picking at classical 1H-NMR interpretation.
