Abstract: Process for the preparation of intermediates that are useful in the synthesis of active pharmaceutical ingredients (API), in particular active in the central nervous system.

Abstract: A process for the preparation of (R)-2-(3-diisopropylamino-1-phenylpropyl)-4-(hydroxymethyl)-phenol isobutyrate (Fesoterodine) or a pharmaceutically acceptable salt thereof having low content in impurities.

Abstract: A process for the preparation of (R)-2-(3-diisopropylamino-1-phenylpropyl)-4-(hydroxymethyl)-phenol isobutyrate (Fesoterodine) or a pharmaceutically acceptable salt thereof having low content in impurities.

Abstract: The invention provides a novel method for the preparation of intermediates useful in a process designed to obtain known 1,2,4-triaminobenzene compounds, and in particular a specific compound thereof having known anticonvulsant activity. Unlike known methods, the novel method does not require advance protection of the amino groups present on the substrate.

Abstract: Disclosed is a process for the preparation of (R)-2-(3-diisopropylamino-1-phenylpropyl)-4-(hydroxymethyl)-phenol isobutyrate (Fesoterodine) or a pharmaceutically acceptable salt thereof having a low content of impurities such as tolterodine and tolterodine isobutyrate.

Abstract: The invention relates to an improved process for the preparation of poly-?-glutamic acids which comprises the polymerization of tertiary ?-esters of ?-glutamic acid N-carboxy anhydride with appropriate solvents and initiators, followed by acid hydrolysis of the resulting poly-?-glutamic acid-?-ester. The process is particularly advantageous in that it allows one to carefully control the molecular weight of the resulting poly-?-glutamic acid. The invention also relates to poly-?-glutamic acids capped at the amino terminus with carboxylic acids or amino acids and to a process for the preparation thereof.

Abstract: The present invention relates to processes for the preparation of 8-(3R)-3-aminopiperidinyl)-7-butyn-2-yl-3 -methyl-1-(4-methyl-quinazolin-2-ylmethyl)-3,7-dihydropurine-2,6-dione and novel intermediates useful in its synthesis.

Abstract: Process for the preparation of 4-[1-oxo-4-[4-(hydroxyphenylmethyl)-1-piperidinyl]butyl]-?,?-dimethylbenzenacetic acid, which is an intermediate useful in the preparation of fexofenadine, by hydrating asymmetric alkynes.

Abstract: A process for the preparation of (R)—N-propargyl-1-aminoindane, or a salt thereof, comprising reacting 1-indanone with propargylamine, in presence of a mixture of sodium borohydride and acetic acid, to obtain N-propargyl-1-aminoindane; and its conversion into (R)—N-propargyl-1-aminoindane or a salt thereof.
