Patent number: 7282606Abstract: The present invention discloses a new process for the synthesis of tamsulosin and its aralkylamine derivatives, especially (R)-(?)-5-{2-[2-(2-alkoxyphenoxy) ethylamino]propyl}-2-alkoxybenzenesulfonamides having the following formula 1 (where R1 and R2 represent C1-C4 alkyl groups) and their hydrochloride thereof, and other various pharmaceutical used salts. Tamsulosin hydrochloride (R1=Et, R2=Me, in its hydrochloride salt form) is an antagonist of ?-A adrenoceptors in the prostate. Tamsulosin•HCl occurs as white crystals, which melt with decomposition at approximately 230° C. It is sparingly soluble in water and in methanol, slightly soluble in glacial acetic acid and in ethanol, and practically insoluble in ether.Type: GrantFiled: July 13, 2005Date of Patent: October 16, 2007Assignees: Well-Being Biochemical Corp., Taiwan Biotech Co., Ltd.Inventors: Ru Hwu Jih, Shwu Chen Tsay, Balaachary Magendran, Subhasish K.
