In the present invention, compounds having formula (IX) prepared via the process F from Step A (and / or its enantiomer) may be very produced as pure compounds. Compounds of formula (IX) which can be obtained by the present invention typically have a quality below.

The content of the diastereomer represented by the formula (X): 0.1% less than the content of the enantiomers represented by the formula (XI): 1.0% less than the formula (XII) and the double bond represented by the formula (XIII) The total content of regioisomers: less than 0.5% (Note that each content is calculated from the area percentage of the free form of formula (IX) (VII) in the by test High Performance Liquid Chromatography) [formula 23] [of 24]

　Next, the present invention is described by examples in detail, the present invention is, which however shall not be construed as limited thereto.
The internal standard substance in a magnetic resonance spectra (NMR), and using tetramethylsilane and abbreviations indicate the multiplicity, s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet, and brs = It shows a broad singlet.
In the name of the compound, “R” and “S” indicate the absolute configuration at the asymmetric carbon. Furthermore, “RS” and “SR” indicates that the asymmetric carbon atom is racemic. In addition, “(1RS, and 5SR) -” if such a can shows the relative arrangement of the 1-position and the 5-position, as well shows only one of the diastereomers, its diastereomers are racemic We show that.
In the name of the compound, “E” and “Z” indicates the arrangement of positional isomers in the structure of the compound having a position isomerism.

“EZ” and “ZE” indicates that it is a mixture of regioisomers. Way more notation, is in accordance with the conventions in this area of the normal.
