Patent number: 9403770Abstract: A process for preparing fexofenadine is described, which provides for the hydrolysis of 4-[4-[4-(hydroxydiphenylmethyl)-1-piperidyl]-1-oxobutyl]-?,?-dimethylbenzeneacetic acid-alkyl ester, in a mixture of water and optionally an organic solvent, in the presence of a base; the carboxylate salt of 4-[4-[4-(hydroxydiphenylmethyl)-1-piperidyl]-1-oxobutyl]-?,?-dimethylbenzeneacetic acid is thus obtained, which is then directly reduced as carboxylate in a basic environment with hydrogen in the presence of a suitable hydrogenation catalyst to give the carboxylate of fexofenadine, which is precipitated by neutralization of the solution.Type: GrantFiled: July 25, 2007Date of Patent: August 2, 2016Assignee: Euticals SPAInventors: Giorgio Bertolini, Maurizio Gallina, Giuseppe Motta, Domenico Vergani

Patent number: 8791287Abstract: The object of the present invention is a new process for the synthesis of tapentadol, both as free base and in hydrochloride form, which comprises the step of alkylation of the ketone (VII) to yield the compound (VIII), as reported in Diagram 1, with high stereoselectivity due to the presence of the benzyl group as substituent of the amino group. It was surprisingly found that this substitution shifts the keto-enol equilibrium towards the desired enantiomer and amplifies the capacity of the stereocenter present in the compound (VII) to orient the nucleophilic addition of the organometallic compound at the carbonyl towards the desired stereoisomer. This substitution thus allows obtaining a considerable increase of the yields in this step, and consequently allows significantly increasing the overall yield of the entire tapentadol synthesis process. A further object of the present invention is constituted by the tapentadol free base in solid form, obtainable by means of the process of the invention.Type: GrantFiled: June 20, 2011Date of Patent: July 29, 2014Assignee: Euticals S.p.A.Inventors: Giuseppe Motta, Domenico Vergani, Giorgio Bertolini, Nicola Landoni

Patent number: 8729308Abstract: The present invention refers to a new process for the synthesis of tapentadol comprising the quantitative resolution of the racemic mixture (V) to obtain the stereoisomer of (S)-3-(dimethylamino)-2-methyl-1-(3-nitrophenyl)-propan-1-one (VII) according to the Scheme 2 below using the (2R,3R)—O,O?-dibenzoyltartaric chiral acid wherein said resolution is quantitative. The present invention also refers to some intermediate compounds of the new synthesis process of tapentadol.Type: GrantFiled: November 30, 2010Date of Patent: May 20, 2014Assignee: Euticals S.p.A.Inventors: Giuseppe Motta, Domenico Vergani, Giorgio Bertolini

Patent number: 6148741Abstract: The table has a table top portion (A) intended for use as a working surface and a table top portion (B) intended for use as an additional supporting surface. The two table top portions (A,B) are adjustable in height conjointly or separately. The vertical member for supporting the table top comprises at least two tubular members arranged one into the other so as to be axially movable relative to each other, drive means adapted to impart an axial motion to the movable tubular members, and control means arranged so as to permit a conjoint height-adjustment of the two table top portions (A,B) or a separate height-adjustment of one of the two table top portions (A,B) relative to the other.Type: GrantFiled: November 17, 1998Date of Patent: November 21, 2000Assignee: UNIFOR S.p.A.Inventor: Giuseppe Motta
