- the process for preparing the compound of formula (IA) comprises the reaction of a compound of formula (II) with a compound of formula (III),
- reaction is followed by a salification step by addition of fumaric acid.
- the process for preparing the compound of formula (I) comprises the step of adding base to the compound of formula (IA).
- the reaction of the compound of formula (II) with the compound of formula (III) can be carried out as described in WO 02/44139.
- This reaction may be carried out in an organic solvent at a temperature between room temperature and the reflux temperature of the solvent.
- ambient temperature is meant a temperature of between 18 ° C and 25 ° C.
- a solvent there may be mentioned ethanol or trimethylorthoformate.
- sodium borohydride (NaBH 4 ) or a derivative thereof (such as NaBH 3 CN) is added.
- the reaction mixture is preferably stirred at a temperature between 0 ° C. and room temperature.
- the reaction mixture obtained can be used as it is for the following of the reaction or can be extracted using an organic solvent, such as ethyl acetate, washed, dried and evaporated according to routine methods to be engaged in the subsequent salification step.
