  • Patent number: 6841679
    Abstract: A compound of the general formula (1), in which: Y denotes hydrogen, a halogen or a C1-4 alkyl group; X1 and X2 denote, independently of each other, hydrogen, a halogen, a C1-4 alkoxy, C1-6 alkyl, CF3, CH3S CH3SO2 or NO2 group; and R1 and R2 denote independently of each other, hydrogen or a C1-5 alkyl group, with the proviso that R1 and R2 do not both denote hydrogen, or a salt thereof, and is prepared by a multi-step process, the last step of which comprises reducing a compound of the general formula (6), in which Y, X1, X2, R1 and R2 are as defined above with an appropriate reducing agent, such as Zn, and, if desired, converting the compound of formula (1) thus obtained, into a salt. The products of this process are known to have useful pharmacological properties, e.g. as anxiolytics.

  • Publication number: 20020151714
    Abstract: The invention concerns a process for preparing 1,4-disubstituted piperidine compounds of formula (I), in which Y =-(CH2) n , n being 0. 1. 2 or 3; oxygen; sulphur; vinyl, -CH 2 -0-; -0-CH 2; -CH 2 -S- or -S-CH 2 , and R and Z mean substituents known per se. Compounds in which Z means -CH 2 -CH 2 - are produced in that the correspondingly substituted 5,6-dihydro- 11 H -benzo[5,6]-cyclohepta-[1,2-b] pyridin-11-one compound is reacted with the corresponding 1-substituted 4-piperidone in a single process step by means of reductive dimerization in the presence of a finely dispersed metal of the IVth and/or Vth and/or VIth subgroup of the periodic table of elements or a low-valent oxidation stage of a corresponding metal compound of this type, the finely dispersed metal or the low-valent oxidation stage being produced in situ by means of a reducing agent and in the presence of an inert solvent. Preferably 4-(5.

  • Patent number: 6218542
    Abstract: A new Process of preparing cisapride, and the pharmaceutically acceptable acid addition salts thereof, by reductively aminating 1-[3-(4-fluorophenoxy)-propyl]-3-methoxy-4-piperidinone in the presence of benzylamine under hydrogen in a reaction-inert solvent, yielding 1-[3-(4-fluorophenoxy)-propyl]-3-methoxy-4-piperidinamine having a cis/trans ratio of about 93/7, which is enriched in the amount of cis-stereoisomer by converting it into its acid addition salt, by treatment with a suitable inorganic acid, in an appropriate solvent, subsequent crystallisation and conversion to its free base form by treatment with an appropriate base, yielding 1-[3-(4-fluorophenoxy)-propyl]-3-methoxy-4-piperidinamine having a cis/trans ratio of equal to or higher than 98/2.

  • Patent number: 6160020
    Abstract: Isolated salts of acetaminophen are disclosed. Alkali metal and alkaline-earth metal salts of acetaminophen were formed by reacting the free acid of acetaminophen with the corresponding metal hydroxide and then immediately isolating the resulting salt. These salts have been found to be more water soluble and less bitter in taste than the free acid form of acetaminophen. The isolated salts may also be combined with other active ingredients.
