Procedure

9 ml of an aqueous 5N hydrochloric acid solution are added to a solution of 1.7 g of tert-butyl 3-(2-amino-4,5-dimethylphenylcarbamoyl)-2,4,5,7-tetrahydropyrazolo[3,4-c]pyridine-6-carboxylate in 40 ml of ethanol. After stirring at 80° C. for 60 hours, the reaction medium is brought back to ambient temperature. The precipitate formed is recovered by filtration through sintered glass and dried. 1.04 g of 3-(5,6-dimethyl-1H-benzimidazol-2-yl)-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-c]pyridine hydrochloride are thus obtained in the form of a beige powder, the characteristics of which are as follows:
