Definitions
- the present application relates to a process for preparing a combretastatin derivative of formula (I) or (II):
- the Applicant has developed an alternative method of preparing compounds (I) or (II) which is based on the use of the intermediates P 2 or P ' 2 described below.
- This method has the advantage of postponing the step during which a cytotoxic intermediate is formed.
- This alternative method therefore has fewer steps including toxic compounds, which facilitates its management from an industrial point of view.
- the invention relates to a process for preparing a combretastatin derivative of formula (I) or (II):
- a " designating the anion associated with an acid AH, comprising the following steps:
- Ar denotes an aryl group chosen from phenyl or thienyl, optionally substituted with a (CrC 4 ) alkyl, (CrC 4 ) alkoxy or halogen group, with:
- R represents a phenyl group optionally substituted with a (CrC 4 ) alkoxy group and R 'represents a hydrogen atom;
- the invention also relates to a compound of formula P2:
- R represents a phenyl group optionally substituted with a (CrC 4 ) alkoxy group and R 'represents a hydrogen atom;
- X represents boc, Fmoc or CBZ.
- the invention also relates to the compound of formula P'2:
- PGi represents a protecting group of the alcohol function and X represents boc, Fmoc or CBZ.
- R and R ' may for example both represent a methyl group (Me) or may together with the carbon atom to which they are connected form the cyclohexyl group.
- X can for example represent boc.
- PG1 may for example represent one of the following protective groups: THP (tetrahydropyran), MEM (methoxyethoxymethyl), boc, trityl or acetyl (Ac).
- Ar may be phenyl or thienyl, optionally substituted with (C 1 -C 4 ) alkyl or (C 1 -C 4 ) alkoxy.
- a " may denote CI " .
- the invention also relates to the use of one of the two compounds P2 and P'2 as an intermediate compound in the preparation of a compound of formula (I) or (II).

At the end of this coupling, P 2 or P 2 are respectively obtained.
- X represents boc, Fmoc or CBZ.
- PG1 denotes a group protecting the alcohol function
- boc, Fmoc and CBZ respectively denote the tert-butoxycarbonyl, 9-fluorenylmethoxycarbonyl and benzyloxycarbonyl groups.
- a protecting group is a chemical entity which is introduced on a molecule during a so-called protection step by modification of a chemical group making it possible to improve the chemo-selectivity of a reaction by avoiding undesired side reactions at the level of said chemical group and which is released in a subsequent deprotection step.
- PG1 may be for example THP (tetrahydropyran), MEM (methoxyethoxymethyl), boc, trityl or acetyl group (Ac).
- Coupling is advantageously carried out in the presence of an acid activator.
- acid activator denotes a compound whose function is to make the -COOH acid function of Pi or ⁇ more reactive in order to promote the formation of an amide bond.
- acid activators reference may be made to ChemFiles Vol.7, No. 2, page 3 edited by Aldrich Chemical or Tetrahedron report No. 672, 2004, 60, 2447- 2467, "Recent Development of Peptide Coupling Reagents in Organic Synthesis".

In the presence of the acidic activator, an intermediate, isolable or otherwise, may be formed comprising an activated acid function of the form -COZ; for example, in the case of pivaloyl chloride, Z represents -OtBu.
- the coupling may be conducted in a solvent such as for example a chlorinated solvent, e.g. dichloromethane (DCM), an ether, e.g. THF or an aromatic solvent, e.g. toluene at a temperature of between 0 ° C and 20 ° C.

- Ar denotes an aryl group selected from phenyl or thienyl, optionally substituted by a (CrC 4 ) alkyl or (CrC 4
- P 3 is obtained by the reaction of the 3,4,5-trimethoxybenzyl halide with the corresponding triarylphosphine PAr 3 .
- a chloride or bromide is preferably used.
- An example of P 3 is triphenyl (3,4,5-trimethoxybenzyl) phosphonium chloride which is described in p.102 of J. Fluor. Chem. 2003, 123, 101-108 or its bromide equivalent which is described in p.15-16 of WO 02/06279.
- the solvent of this reaction may be, for example, toluene, THF, dimethylformamide (DM F), chloroform, DCM, trifluorotoluene, a mixture of these solvents or an aqueous biphasic mixture, for example the chloroform / water.
- the base used is preferably a strong base such as, for example, NaHMDS (sodium bis (trimethylsilyl) amide CAS [1070-89-9]), KHMDS (potassium bis (trimethylsilyl) amide, CAS [ 40949-94-8]), sodium methoxide, sodium amide, sodium hydroxide.
- the base may be brought into contact with the phosphonium salt P 3 , and then the aldehyde P 2 or P ' 2 may be cast on the phosphonium salt P 3 , which has been brought into contact with the base beforehand.
- the base is cast on the mixture formed by the aldehyde and the phosphonium salt.
- the skilled person may refer to "Greene's Protective Groups in Organic Synthesis", 4th edition, isbn 978-0-471 -69,754 to 1 to find if any of these conditions.
- the deprotection can be conducted in the presence of an organic or inorganic HA acid. In this case, the deprotection leads to the compound P 5 in salt form.
- the deprotection can be conducted in the presence of a base B, organic or mineral. In this case, the deprotection leads to the compound P ' 5 in base form.
- the temperature of the deprotection reaction is preferably from 0 ° C to 50 ° C.
- the acid may be a strong acid such as for example hydrochloric acid, which leads to the hydrochloride.
- the base may be, for example, sodium hydroxide.
