Introducing a new discovery about 166591-85-1, Name is 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid
AN IMPROVED PROCESS FOR THE PREPARATION OF ALFUZOSIN HYDROCHLORIDE
The present invention relates to an improved process for the preparation of Alfuzosin hydrochloride of formula (I) by reacting N-(3-aminopropyl)-6,7-dimethoxy-N-methylquinazoline-2,4-diamine of Formula (II) with 1-(tetrahydrofuran-2-ylcarbonyl)-1H-imidazole of formula (IV) using acetonitrile as an organic solvent. This invention also relates to a method for the purification of N-(3-aminopropyl)-6,7-dimethoxy-N-methylquinazoline-2,4-diamine of formula (II), which is a key starting material of Alfuzosin hydrochloride by making its corresponding salt of formula (III) using an organic di-carboxylic acid in an alcoholic solvent wherein, A is denoted as a corresponding moiety of organic di-carboxylic acid.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, you can also check out more blogs about166591-85-1
