    摘要: A process for the preparation of compounds of formula HO-A-ONO2   (I) wherein A is a C2-C6 alkylene chain by nitration of the corresponding alkanediols with “stabilised” nitric acid is herein disclosed. The process is safer to operators and allows to obtain advantageous yields on an industrial scale.

    摘要: A process for the preparation of a compound of formula (I), or a salt thereof wherein R is H, C1-C8 alkyl, aryl or aryl-C1-C8 alkyl; comprising the reaction between a compound of formula (II) wherein R1 and R2 are independently hydrogen, C1-C8 alkyl, aryl, aryl-C1-C8 alkyl, or R1 and R2, taken together, form a —(CH2)m—V—(CH2)n— group, in which V is NR3 or C(R3)2 wherein R3 is hydrogen, C1-C8 alkyl, aryl or aryl-C1-C8 alkyl; and m and n, which can be the same or different, are 1 or 2; with a compound of formula (III) in which R4 and R5 are independently C1-C8 alkyl, aryl or aryl-C1-C8 alkyl; in the presence of a Ni (II) salt, an organic ligand and a basic agent, to obtain a compound of formula (I) wherein R is C1-C8 alkyl, aryl or aryl-C1-C8 alkyl and, if desired, its conversion to a compound of formula (I) wherein R is hydrogen or to a salt thereof.

    摘要: A novel process prepares tolterodine, i.e. (R)-N,N-diisopropyl-3-(2-hydroxy-5-methylphenyl)-3-phenylpropanamine, in the racemic form, as well as intermediates useful for its preparation. Tolterodine free base may be prepared by reacting diisopropyl-(3-phenyl-3-p-tolyloxy-propyl)-amine and 60% aqueous sulfuric acid for three hours under stirring at room temperature. The reaction mixture is then poured over ice/water and then alkalized with 50% NaOH.
