Definitions
- This invention relates to a process for the industrial scale preparation of the antifungal agent eberconazole (I), which involves two new intermediates, as well as these intermediates as such.
- the l- (2, 4-dichloro-10, ll-dihydro-5H-dibenzo ra, di-cyclohepten-5-yl) -lH-imidazole, of formula (I) and CAS Registry Number 128326-82-9, is an antifungal agent called eberconazole (International Common Denomination). Normally it is used in nitrate therapy. Eberconazole (I) was first described in European patent application EP 392,326-A and in its equivalent patents. Eberconazole (I) is very difficult to prepare on an industrial scale.
- An aspect of the present invention is to provide an improved process for preparing eberconazole (I) and its pharmaceutically acceptable salts.
- This process comprises the four steps (a) - (b) mentioned above, preceded by a new step characterized in that 2- [2- (3,5-dichlorophenyl) ethyl] benzoic acid (V) is prepared by reduction, preferably by Catalytic hydrogenation of 2- [2- (3, 5-dichlorophenyl) -ethenyl] enzoic acid (VI), this compound being either in its E form, or in its Z form, or as a mixture of both isomers.
- the E / Z isomer of (VI) is inconsequential since it disappears when the double bond is reduced.
- the process further comprises the final addition of the corresponding acid (eg nitric acid).
- a certain salt eg nitrate
- the corresponding acid eg nitric acid
- the process of the present invention comprises the preparation of 2- [2- (3, 5-dichlorophenyl) ethenyl] benzoic acid (VI) by hydrolysis of any of its esters of formula (VII), where R is (C1-C4) -alkyl and preferably R is methyl.
- the process of the present invention further comprises preparing the ester of formula (VII) by a Wittig reaction between 3,5-dichlorobenzaldehyde (X) and phosphorus ilide obtained by the basic treatment of a halide of [[(2-Alkoxycarbonyl) phenyl] methyl] triphenylphosphonium of formula (XI), where R is (C1-C4) -alkyl and Y is 01, Br or I.
- R is (C1-C4) -alkyl and Y is 01, Br or I.
- the process is preferred when R is methyl; and even more preferred, when Y is bromine.
- Another aspect of the present invention is to provide chemically novel intermediates that are crucial for the preparation of eberconazole according to the described process.
- R is selected from the group (Cl-C4) -alkyl.
- R is selected from the group (Cl-C4) -alkyl.
- the compound (VII) where R is methyl is also part of the present invention.
- the process of the present invention uses the well-known synthetic methods of the Wittig reaction, the hydrolysis of esters and the reduction of alkenes (particularly, catalytic hydrogenation).
- Catalysts, solvents and reaction conditions can be easily modified without changing the essential characteristics of the process.
- the Wittig reaction can be carried out in an aprotic and polar solvent such as dimethylformamide, with a strong base such as sodium hydride.
- the hydrolysis of esters It can be done with sodium hydroxide in an aqueous alcohol.
- Catalytic hydrogenation can be carried out at atmospheric pressure with Pd / C as catalyst.
- the main advantage of the process of the present invention compared to those known in the art, is that it is easy to increase the scale of the reactions involved. This is because they can be done at a moderate temperature, without the need for a strict inert atmosphere, and without the risk of inflammation.
- the availability of the starting materials, the number of steps and the yields of the reactions are also good for their industrialization.
- a solution of 44.0 of methyl 2- [2- (3,5-dichlorophenyl) ethenyl] benzoate in 720 ml of a mixture 2 was prepared : 1 methanol and NaOH (aq) 2N.
- the mixture was refluxed for 14 hours, and allowed to cool to room temperature.
- the solvents were removed at reduced pressure and the residue obtained was diluted with 400 mL of water.
- Methylene chloride was added and the organic phase was separated.
- the pH of the aqueous phase was adjusted to a range of 2-3 with 4N HCl (aq), and extracted with two portions of ethyl acetate.
