A process for the preparation of a compound of formula (I), the process comprising the steps of (i) adding a solution of a compound of formula (II) in aqueous hydrochloric acid to an aqueous solution of sodium cyanide at a temperature in the range -5 to 10 ~C, and (ii) mixing the resulting mixture at a pH in the range 8.5-9.5 and a temperature in the range -5 to 5 ~C for 15-24 hours under efficient agitation conditions, the concentration of sodium cyanide in the resulting mixture being greater than 2.4 molar.

La présente invention concerne un procédé permettant d'élaborer un composé représenté par la formule générale (I). Pour ce procédé, on commence par (i) prendre un composé représenté par la formule particulière (II) en solution dans une solution aqueuse d'acide chlorhydrique et à l'ajouter à une solution aqueuse de cyanure de sodium à une température comprise entre -5·C et 10·C. On prend ensuite cette mixture d'un pH de 8,5 à 9,5 que l'on mélange (ii) par agitation à une température comprise entre -5·C et 5·C pendant 15 à 24 heures dans des conditions d'agitation satisfaisantes, la teneur molaire en cyanure de sodium de la mixture obtenue étant supérieure à 2,4.
