  • One of the subjects of the present invention is to obtain during the process, a majority of one of the two isomers, i.e. at least greater than 50% (isomer called form A, corresponding to the pharmacologically active compound of formula (I), which is not the case for the process according to WO99/29716 during which the active isomer A obtained during the process before purification on a chromatographic column is in the minority.
  • Another objective of the present invention is to avoid purifications of the intermediate products by chromatography and to obtain crystallized products which allows a significant improvement in yields.
  • a subject of the invention is a process for the preparation of compounds of formula (I) in which R represents a linear or branched or cyclic chain containing up to 30 carbon atoms, optionally containing one or more heteroatoms and one or more heterocycles comprising the following stages a) A compound of formula (II) is subjected to the action of an acid of formula R—CO 2 H, R being as defined above, said acid being, if appropriate, in an isolated or non isolated activated form, in order to obtain the compound of formula (III) b) if appropriate, the compound of formula (III) is subjected to an alkylation reaction of the alcohol in position 5 by the action of an alcohol of formula Alk—OH in the presence of PPTS, Alk being an Alkyl radical containing 1 to 4 carbon atoms, in order to obtain the compound of formula (III′) c) the compound of formula (III) or (III′) is subjected to a dehydration reaction, in order to obtain a compound of formula (IV) d)
