14. With the purification by reprecipitation and column chromatography, the relative yield of the isomer I considerably increased (10 - 15%). For HPLC analyses, the reaction mixtures without the purification were used. The relative yield was calculated from the relative peak height of the isomer I for those of all isomers.
